7 Detailed Description
7.1 Overview
The TMP100 and TMP101 devices are digital temperature sensors optimal for thermal management and thermal
protection applications. The TMP100 and TMP101 devices are Two-Wire, SMBus, and I2C interface-compatible.
These devices are specified over a operating temperature range of −55°C to 125°C. The Functional Block
Diagram section shows the internal block diagrams of the TMP100 and TMP101 devices.
The temperature sensor in the TMP100 and TMP101 devices is the chip itself. Thermal paths run through the
package leads as well as the plastic package. The package leads provide the primary thermal path because of
the lower thermal resistance of the metal. The GND pin of the TMP100 or TMP101 is directly connected to the
metal lead frame, and is the best choice for thermal input.

7.3 Feature Description
7.3.1 Digital Temperature Output
The digital output from each temperature measurement conversion is stored in the read-only Temperature
Register. The Temperature Register of the TMP100 or TMP101 device is a 12-bit, read-only register that stores
the output of the most recent conversion. Two bytes must be read to obtain data and are listed in Table 6 and
Table 7. The first 12 bits are used to indicate temperature with all the remaining bits equal to zero. The data
format for temperature is listed in Table 1. Negative numbers are represented in binary twos complement format.
Following power-up or reset, the temperature register reads 0°C until the first conversion is complete.
The user can obtain 9, 10, 11, or 12 bits of resolution by addressing the Configuration Register and setting the
resolution bits accordingly. For 9-, 10-, or 11-bit resolution, the most significant bits (MSBs) in the Temperature
Register are used with the unused least significant bits (LSBs) set to zero.

7.3.2 Serial Interface
The TMP100 and TMP101 devices operate only as slave devices on the SMBus, Two-Wire, and I2C interface-
compatible bus. Connections to the bus are made through the open-drain I/O lines SDA and SCL. The TMP100
and TMP101 devices support the transmission protocol for fast (up to 400 kHz) and high-speed (up to 2 MHz)
modes. All data bytes are transmitted MSB first.
7.3.2.1 Bus Overview
The device that initiates the transfer is called a master, and the devices controlled by the master are slaves. The
bus must be controlled by a master device that generates the serial clock (SCL), controls the bus access, and
generates the START and STOP conditions.
To address a specific device, a START condition is initiated, indicated by pulling the data line (SDA) from a HIGH
to LOW logic level while SCL is HIGH. All slaves on the bus shift in the slave address byte, with the last bit
indicating whether a read or write operation is intended. During the ninth clock pulse, the slave being addressed
responds to the master by generating an Acknowledge and pulling SDA LOW.
Data transfer is then initiated and sent over eight clock pulses followed by an Acknowledge Bit. During data
transfer, SDA must remain stable while SCL is HIGH because any change in SDA while SCL is HIGH is
interpreted as a control signal.
When all data are transferred, the master generates a STOP condition indicated by pulling SDA from LOW to
HIGH, while SCL is HIGH.

7.3.2.2 Serial Bus Address
To program the TMP100 and TMP101 devices, the master must first address slave devices through a slave
address byte. The slave address byte consists of seven address bits and a direction bit indicating the intent of
executing a read or write operation.
The TMP100 device features two address pins to allow up to eight devices to be addressed on a single I2C
interface. Table 2 describes the pin logic levels used to properly connect up to eight devices. Float indicates the
pin is left unconnected. The state of pins ADD0 and ADD1 is sampled on the first I2C bus communication and
must be set before any activity on the interface.

The TMP101 device features one address pin and an ALERT pin, allowing up to three devices to be connected
per bus. Pin logic levels are described in Table 3. The address pins of the TMP100 and TMP101 devices are
read after reset or in response to an I2C address acquire request. Following reading, the state of the address
pins is latched to minimize power dissipation associated with detection.

7.3.2.3 Writing and Reading to the TMP100 and TMP101
Accessing a particular register on the TMP100 and TMP101 devices is accomplished by writing the appropriate
value to the Pointer Register. The value for the Pointer Register is the first byte transferred after the I2C slave
address byte with the R/W bit LOW. Every write operation to the TMP100 and TMP101 devices requires a value
for the Pointer Register (see Figure 7).
When reading from the TMP100 and TMP101 devices, the last value stored in the Pointer Register by a write
operation is used to determine which register is read by a read operation. To change the register pointer for a
read operation, a new value must be written to the Pointer Register. This action is accomplished by issuing an
I2C slave address byte with the R/W bit LOW, followed by the Pointer Register Byte. No additional data are
required. The master can then generate a START condition and send the I2C slave address byte with the R/W bit
HIGH to initiate the read command; see Figure 8 for details of this sequence. If repeated reads from the same
register are desired, the Pointer Register bytes do not have to be continually sent because the TMP100 and
TMP101 devices remember the Pointer Register value until that value is changed by the next write operation.

7.3.2.4 Slave Mode Operations
The TMP100 and TMP101 devices can operate as a slave receiver or slave transmitter.
7.3.2.4.1 Slave Receiver Mode
The first byte transmitted by the master is the slave address, with the R/W bit LOW. The TMP100 or TMP101
devices then acknowledges reception of a valid address. The next byte transmitted by the master is the Pointer
Register. The TMP100 or TMP101 devices then acknowledges reception of the Pointer Register byte. The next
byte or bytes are written to the register addressed by the Pointer Register. The TMP100 and TMP101 devices
acknowledge reception of each data byte. The master can terminate data transfer by generating a START or
STOP condition.
7.3.2.4.2 Slave Transmitter Mode
The first byte is transmitted by the master and is the slave address, with the R/W bit HIGH. The slave
acknowledges reception of a valid slave address. The next byte is transmitted by the slave and is the most
significant byte of the register indicated by the Pointer Register. The master acknowledges reception of the data
byte. The next byte transmitted by the slave is the least significant byte. The master acknowledges reception of
the data byte. The master can terminate data transfer by generating a Not-Acknowledge on reception of any data
byte, or generating a START or STOP condition.
7.3.2.5 SMBus Alert Function
The TMP101 device supports the SMBus Alert function. When the TMP101 device is operating in Interrupt Mode
(TM = 1), the ALERT pin of the TMP101 device can be connected as an SMBus Alert signal. When a master
senses that an ALERT condition is present on the ALERT line, the master sends an SMBus Alert command
(00011001) on the bus. If the ALERT pin of the TMP101 device is active, the TMP101 device acknowledges the
SMBus Alert command and responds by returning its slave address on the SDA line. The eighth bit (LSB) of the
slave address byte indicates if the temperature exceeding THIGH or falling below TLOW caused the ALERT
condition. For POL = 0, this bit is LOW if the temperature is greater than or equal to THIGH. This bit is HIGH if
the temperature is less than TLOW. The polarity of this bit is inverted if POL = 1; see Figure 9 for details of this
sequence.
If multiple devices on the bus respond to the SMBus Alert command, arbitration during the slave address portion
of the SMBus alert command determine which device clears its ALERT status. If the TMP101 device wins the
arbitration, its ALERT pin becomes inactive at the completion of the SMBus Alert command. If the TMP101 loses
the arbitration, its ALERT pin remains active.
The TMP100 device also responds to the SMBus ALERT command if its TM bit is set to 1. Because the device
does not have an ALERT pin, the device must periodically poll the device by issuing an SMBus Alert command.
If the TMP100 device generates an ALERT, the device acknowledges the SMBus Alert command and returns its
slave address in the next byte.
7.3.2.6 General Call
The TMP100 and TMP101 devices respond to the I2C General Call address (0000000) if the eighth bit is 0. The
device acknowledges the General Call address and responds to commands in the second byte. If the second
byte is 00000100, the TMP100 and TMP101 devices latch the status of their address pins, but do not reset. If the
second byte is 00000110, the TMP100 and TMP101 devices latch the status of their address pins and reset their
internal registers.
7.3.2.7 High-Speed Mode
In order for the I2C bus to operate at frequencies above 400 kHz, the master device must issue an Hs-mode
master code (00001XXX) as the first byte after a START condition to switch the bus to high-speed operation.
The TMP100 and TMP101 devices do not acknowledge this byte as required by the I2C specification, but do
switch their input filters on SDA and SCL and their output filters on SDA to operate in Hs-mode, allowing
transfers at up to 2 MHz. After the Hs-mode master code is issued, the master transmits an I2C slave address to
initiate a data transfer operation. The bus continues to operate in Hs-mode until a STOP condition occurs on the
bus. Upon receiving the STOP condition, the TMP100 and TMP101 devices switch the input and output filter
back to fast-mode operation.

7.3.2.8 POR (Power-On Reset)
The TMP100 and TMP101 devices both have on-chip, power-on reset circuits that reset the device to default
settings when the device is powered on. This circuit activates when the power supply is less than 0.3 V for more
than 100 ms. If the TMP100 and TMP101 devices are powered down by removing supply voltage from the
device, but the supply voltage is not assured to be less than 0.3 V, TI recommends issuing a General Call reset
command on the I2C interface bus to ensure that the TMP100 and TMP101 devices are completely reset.
7.3.3 Timing Diagrams
The TMP100 and TMP101 devices are Two-Wire, SMBUs, and I2C interface-compatible. Figure 6 to Figure 9
describe the various operations on the TMP100 and TMP101. The following list provides bus definitions.
Parameters for Figure 6 are defined in the Timing Requirements section.
Bus Idle: Both SDA and SCL lines remain HIGH.
Start Data Transfer: A change in the state of the SDA line, from HIGH to LOW, while the SCL line is HIGH,
defines a START condition. Each data transfer is initiated with a START condition.
Stop Data Transfer: A change in the state of the SDA line from LOW to HIGH while the SCL line is HIGH
defines a STOP condition. Each data transfer is terminated with a repeated START or STOP condition.
Data Transfer: The number of data bytes transferred between a START and a STOP condition is not limited and
is determined by the master device. The receiver acknowledges the transfer of data.
Acknowledge: Each receiving device, when addressed, is obliged to generate an Acknowledge bit. A device
that acknowledges must pull down the SDA line during the Acknowledge clock pulse in such a way that the SDA
line is stable LOW during the HIGH period of the Acknowledge clock pulse. Setup and hold times must be taken
into account. On a master receive, the termination of the data transfer can be signaled by the master generating
a Not-Acknowledge on the last byte that is transmitted by the slave.

7.4 Device Functional Modes
7.4.1 Shutdown Mode (SD)
The Shutdown Mode of the TMP100 and TMP101 devices lets the user save maximum power by shutting down
all device circuitry other than the serial interface, which reduces current consumption to less than 1 µA. For the
TMP100 and TMP101 devices, Shutdown Mode is enabled when the SD bit is 1. The device shuts down when
the current conversion is completed. For SD equal to 0, the device maintains continuous conversion.
7.4.2 OS/ALERT (OS)
The TMP100 and TMP101 devices feature a One-Shot Temperature Measurement Mode. When the device is in
Shutdown Mode, writing 1 to the OS/ALERT bit starts a single temperature conversion. The device returns to the
shutdown state at the completion of the single conversion. This feature is useful to reduce power consumption in
the TMP100 and TMP101 devices when continuous monitoring of temperature is not required.
Reading the OS/ALERT bit provides information about the Comparator Mode status. The state of the POL bit
inverts the polarity of data returned from the OS/ALERT bit. For POL = 0, the OS/ALERT reads as 1 until the
temperature equals or exceeds THIGH for the programmed number of consecutive faults, causing the OS/ALERT
bit to read as 0. The OS/ALERT bit continues to read as 0 until the temperature falls below TLOW for the
programmed number of consecutive faults when the OS/ALERT bit again reads as 1. The status of the TM bit
does not affect the status of the OS/ALERT bit.
7.4.3 Thermostat Mode (TM)
The Thermostat Mode bit of the TMP101 device indicates to the device whether to operate in Comparator Mode
(TM = 0) or Interrupt Mode (TM = 1). For more information on comparator and interrupt modes, see the High-
and Low-Limit Registers section.
7.4.3.1 Comparator Mode (TM = 0)
In Comparator Mode (TM = 0), the ALERT pin is activated when the temperature equals or exceeds the value in
the THIGH register and remains active until the temperature falls below the value in the TLOW register. For more
information on the Comparator Mode, see the High- and Low-Limit Registers section.
7.4.3.2 Interrupt Mode (TM = 1)
In Interrupt Mode (TM = 1), the ALERT pin is activated when the temperature exceeds THIGH or goes below the
TLOW registers. The ALERT pin is cleared when the host controller reads the temperature register. For more
information on the interrupt mode, see the High- and Low-Limit Registers section.

Figure 10 shows the internal register structure of the TMP100 and TMP101 devices. The 8-bit Pointer Register of
the TMP100 and TMP101 devices is used to address a given data register. The Pointer Register uses the two
LSBs to identify which of the data registers respond to a read or write command. Table 4 identifies the bits of the
Pointer Register byte. Table 5 describes the pointer address of the registers available in the TMP100 and
TMP101 devices. The power-up reset value of P1 and P0 is 00.

7.5.2 Temperature Register
The Temperature Register of the TMP100 or TMP101 devices is a 12-bit, read-only register that stores the
output of the most recent conversion. Two bytes must be read to obtain data, and are described in Table 6 and
Table 7. The first 12 bits are used to indicate temperature, with all remaining bits equal to zero. Data format for
temperature is summarized in Table 1. Following power-up or reset, the Temperature Register reads 0°C until
the first conversion is complete.

The Configuration Register is an 8-bit read and write register used to store bits that control the operational
modes of the temperature sensor. Read and write operations are performed MSB-first. The format of the
Configuration Register for the TMP100 and TMP101 devices is shown in Table 8, followed by a breakdown of the
register bits. The power-up or reset value of the Configuration Register is all bits equal to 0. The OS/ALERT bit
reads as 1 after power-up or reset value.

7.5.3.1 Shutdown Mode (SD)
The Shutdown Mode of the TMP100 and TMP101 devices allows the user to save maximum power by shutting
down all device circuitry other than the serial interface, which reduces current consumption to less than 1 µA. For
the TMP100 and TMP101 devices, Shutdown Mode is enabled when the SD bit is 1. The device shuts down
when the current conversion is completed. For SD equal to 0, the device maintains continuous conversion.
7.5.3.2 Thermostat Mode (TM)
The Thermostat Mode bit of the TMP101 device indicates to the device whether to operate in Comparator Mode
(TM = 0) or Interrupt Mode (TM = 1). For more information on comparator and interrupt modes, see High- and
Low-Limit Registers.
7.5.3.3 Polarity (POL)
The Polarity bit of the TMP101 device lets the user adjust the polarity of the ALERT pin output. If the POL bit is
set to 0 (default), the ALERT pin becomes active low. When the POL bit is set to 1, the ALERT pin becomes
active high and the state of the ALERT pin is inverted. The operation of the ALERT pin in various modes is
illustrated in Figure 11.

7.5.3.4 Fault Queue (F1, F0)
A fault condition occurs when the measured temperature exceeds the user-defined limits set in the THIGH and
TLOW Registers. Additionally, the number of fault conditions required to generate an alert can be programmed
using the Fault Queue. The Fault Queue is provided to prevent a false alert resulting from environmental noise.
The Fault Queue requires consecutive fault measurements in order to trigger the alert function. If the temperature
falls below TLOW before reaching the number of programmed consecutive faults limit, the count is reset to 0.
Table 9 defines the number of measured faults that can be programmed to trigger an alert condition in the
device.

7.5.3.6 OS/ALERT (OS)
The TMP100 and TMP101 devices feature a One-Shot Temperature Measurement Mode. When the device is in
Shutdown Mode, writing 1 to the OS/ALERT bit starts a single temperature conversion. The device returns to the
shutdown state at the completion of the single conversion. This feature is useful to reduce power consumption in
the TMP100 and TMP101 when continuous temperature monitoring is not required.
Reading the OS/ALERT bit provides information about the Comparator Mode status. The state of the POL bit
inverts the polarity of data returned from the OS/ALERT bit. For POL = 0, the OS/ALERT reads as 1 until the
temperature equals or exceeds THIGH for the programmed number of consecutive faults, causing the OS/ALERT
bit to read as 0. The OS/ALERT bit continues to read as 0 until the temperature falls below TLOW for the
programmed number of consecutive faults when the OS/ALERT bit again reads as 1. The status of the TM bit
does not affect the status of the OS/ALERT bit.
7.5.4 High- and Low-Limit Registers
In Comparator Mode (TM = 0), the ALERT pin of the TMP101 becomes active when the temperature equals or
exceeds the value in THIGH and generates a consecutive number of faults according to fault bits F1 and F0. The
ALERT pin remains active until the temperature falls below the indicated TLOW value for the same number of
faults.
In Interrupt Mode (TM = 1) the ALERT pin becomes active when the temperature equals or exceeds THIGH for a
consecutive number of fault conditions. The ALERT pin remains active until a read operation of any register
occurs or the device successfully responds to the SMBus Alert Response Address. The ALERT pin is also
cleared if the device is placed in Shutdown Mode. When the ALERT pin is cleared, it only becomes active again
by the temperature falling below TLOW. When the temperature falls below TLOW, the ALERT pin becomes active
and remains active until cleared by a read operation of any register or a successful response to the SMBus Alert
Response Address. When the ALERT pin is cleared, the above cycle repeats with the ALERT pin becoming
active when the temperature equals or exceeds THIGH. The ALERT pin can also be cleared by resetting the
device with the General Call Reset command. This action also clears the state of the internal registers in the
device, returning the device to Comparator Mode (TM = 0).
Both operational modes are represented in Figure 11. Table 11, Table 12, Table 13, and Table 14 describe the
format for the THIGH and TLOW registers. Power-up reset values for THIGH and TLOW are: THIGH = 80°C and TLOW
75°C. The format of the data for THIGH and TLOW is the same as for the Temperature Register.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TMP100 and TMP101 devices are used to measure the printed circuit board (PCB) temperature of the board
location where the devices are mounted. The TMP100 features two address pins to allow up to eight devices to
be addressed on a single I2C interface. The TMP101 device features one address pin and an ALERT pin,
allowing up to three devices to be connected per bus. The TMP100 and TMP101 devices require no external
components for operation except for pullup resistors on SCL, SDA, and ALERT (TMP101 device), although a
0.1-μF bypass capacitor is recommended.
The sensing device of the TMP100 and TMP101 devices is the chip itself. Thermal paths run through the
package leads as well as the plastic package. The die flag of the lead frame is connected to GND. The lower
thermal resistance of metal causes the leads to provide the primary thermal path. The GND pin of the TMP100 or
TMP101 device is directly connected to the metal lead frame, and is the best choice for thermal input.

8.2.1 Design Requirements
Figure 13. Typical Connections of the TMP101
The TMP100 and TMP101 devices require pullup resistors on the SCL, SDA, and ALERT (TMP101 device) pins.
The recommended value for the pullup resistor is 5-kΩ. In some applications, the pullup resistor can be lower or
higher than 5-kΩ but must not exceed 3 mA of current on the SCL and SDA pins, and must not exceed 4 mA on
the ALERT (TMP101) pin. A 0.1-μF bypass capacitor is recommended, as shown in Figure 12 and Figure 13.
The SCL, SDA, and ALERT lines can be pulled up to a supply that is equal to or higher than VS through the
pullup resistors. For the TMP100, to configure one of eight different addresses on the bus, connect ADD0 and
ADD1 to either the GND pin, V+ pin, or float. Float indicates the pin is left unconnected. For the TMP101 device,
to configure one of three different addresses on the bus, connect ADD0 to either the GND pin, V+ pin, or float.
8.2.2 Detailed Design Procedure
Place the TMP100 and TMP101 devices in close proximity to the heat source that must be monitored, with a
proper layout for good thermal coupling. This placement ensures that temperature changes are captured within
the shortest possible time interval. To maintain accuracy in applications that require air or surface temperature
measurement, care must be taken to isolate the package and leads from ambient air temperature. A thermally-
conductive adhesive is helpful in achieving accurate surface temperature measurement.

8.2.3 Application Curve
Figure 14 shows the step response of the TMP100 and TMP101 devices to a submersion in an oil bath of 100ºC
from room temperature (27ºC). The time constant, or the time for the output to reach 63% of the input step, is
0.9 s. The time-constant result depends on the PCB that the TMP100 and TMP101 devices are mounted. For
this test, the TMP100 and TMP101 devices are soldered to a two-layer PCB that measures 0.375 inch × 0.437
inch.

9 Power Supply Recommendations
The TMP100 and TMP101 devices operate with power supply in the range of 2.7 V to 5.5 V. A power-supply
bypass capacitor is required for stability; place this capacitor as close as possible to the supply and ground pins
of the device. A typical value for this supply bypass capacitor is 0.01 μF. Applications with noisy or high-
impedance power supplies can require additional decoupling capacitors to reject power-supply noise.
10 Layout
10.1 Layout Guidelines
Place the power-supply bypass capacitor as close as possible to the supply and ground pins. The recommended
value of this bypass capacitor is 0.01 μF. Additional decoupling capacitance can be added to compensate for
noisy or high-impedance power supplies. Pull up the open-drain output pins SDA , SCL, and ALERT (TMP101)
through 5-kΩ pullup resistors.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
