LM26 SOT-23, ±3°C Accurate, Factory-Preset Thermostat
1 Features
3 Description
The LM26 is a precision, single digital-output, low-
1
•
Internal Comparator With Pin Programmable 2°C
or 10°C Hysteresis
power thermostat comprised of an internal reference,
DAC, temperature sensor and comparator. Utilizing
factory programming, it can be manufactured with
different trip points as well as different digital output
functionality. The trip point (TOS) can be preset at the
factory to any temperature in the range of −55°C to
110°C in 1°C increments. The LM26 has one digital
output (OS/OS/US/US), one digital input (HYST) and
one analog output (VTEMP). The digital output stage
can be preset as either open-drain or push-pull. In
addition, it can be factory programmed to be active
HIGH or LOW. The digital output can be factory
programmed to indicate an over temperature
shutdown event (OS or OS) or an under temperature
shutdown event (US or US). When preset as an
overtemperature shutdown (OS) it will go LOW to
indicate that the die temperature is over the internally
preset TOS and go HIGH when the temperature goes
below (TOS–THYST). Similarly, when preprogrammed
as an undertemperature shutdown (US) it will go
HIGH to indicate that the temperature is below TUS
and go LOW when the temperature is above
(TUS+THYST). The typical hysteresis, THYST, can be set
to 2°C or 10°C and is controlled by the state of the
HYST pin. A VTEMP analog output provides a voltage
that is proportional to temperature and has a −10.82
mV/°C output slope.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) When the input voltage (VI) at any pin exceeds the power supply (VI < GND or VI > V+), the current at that pin should be limited to 5 mA.
The 20-mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input
current of 5 mA to four. Under normal operating conditions the maximum current that pins 2, 4 or 5 can handle is limited to 5 mA each.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (maximum junction temperature),
θJA (junction to ambient thermal resistance) and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PD = (TJMAX–TA) / θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device, TJMAX
= 150°C. For this device the typical thermal resistance (θJA) of the different package types when board mounted follow:

increase by 1.28 mW when IOUT = 3.2 mA and VOUT = 0.4 V. With a thermal resistance of 250°C/W, this power dissipation would cause
an increase in the die temperature of about 0.32°C due to self heating. Self heating is not included in the trip point accuracy
specification.

8 Detailed Description
8.1 Overview
The LM26 is a factory preset thermostat (temperature switch) that includes an integrated temperature sensor,
reference voltage, DAC and comparator. The LM26 can be factory programmed to have a trip point anywhere in
the range of −55°C to +120°C. The output functionality can also be changed during the manufacturing process,
as described in the functional block diagrams. Available options include:
•
•
•
•
OS: active low, open drain that indicates an over temperature shutdown event (most common)
US: active low, open-drain that indicates an under temperature shutdown event
OS: active high, push-pull that indicates an over temperature shutdown event
US: active high, push-pull that indicates an under temperature shutdown event
The internal temperature sensor is brought out on the VTEMP pin and can be used to determine the temperature
that the LM26 is reading by monitoring with an ADC. It has a negative temperature coefficient (NTC) of
approximately -10mV/°C. This pin also allows after assembly PCB testing (see section After Assembly PCB
Testing for more details).
The comparator hysteresis is selectable by the state of the HYST. Two values are available 10°C or 2°C.
Comparator hysteresis is essential, as it prevents comparator output chattering when the temperature is at the
comparator threshold set point (REF as shown in the functional block diagrams). Once the comparator trips the
hysteresis function changes the comparator threshold (REF) level such that the output remains locked in the
active state. The threshold is changed by either 10°C or 2°C as programmed by the state of the HYST pin.

8.3 Feature Description
8.3.1 Hysteresis
The HYST pin level sets the comparator hysteresis. Setting the HYST pin to GND selects 10°C hysteresis, while
setting it to V+ selects 2°C. A series resistor can be used for protection purposes. The input leakage current of
the pin is less than 10 µA. The value of the resistor will depend on the value of V+ as well as the leakage current.
For example with V+ = 3.3 V the input threshold level for VIH = 0.8 × 3.3 V = 2.64 V, thus the voltage drop across
the resistor should be less than 0.66 V. The 10-µA input leakage current requires the resistor value to be less
than 66 kΩ.
8.3.2 VTEMP Output
The VTEMP output provides an output voltage that can be used to determine the temperature reading of the LM26.
The temperature reading of the LM26 can be calculated using the equation:
-6
-2
VO = ( - 3.47 ´10 ´(T - 30)2 ) + (1.082´10 ´(T - 30)) + 1.8015 V
(1)
or
1.8015 - VTEMP
T = -1525.04 + 2.4182´106 +
3.479 ´10-6
(2)
The VTEMP output has very weak drive capability (1-µA source, 40-µA sink). So care should be taken when
attaching circuitry to this pin. Capacitive loading may cause the VTEMP output to oscillate. Simply adding a resistor
in series as shown in Figure 6 and Figure 7 will prevent oscillations from occurring. To determine the value of the
resistor follow the guidelines given in Table 1. The same value resistor will work for either placement of the
resistor. If an additional capacitive load is placed directly on the LM26 output, rather than across CLOAD, it should
be at least a factor of 10 smaller than CLOAD
.

8.4 Device Functional Modes
The LM26 after factory programming has two functional modes one with 2°C Hysteresis and the other with 10°C
hysteresis as programmed by the level of the HYST pin. Selection of the level will depend on the system noise
and the temperature transition rate.
8.4.1 After Assembly PCB Testing
The LM26's VTEMP output allows after-assembly PCB testing by following a simple test procedure. Simply
measuring the VTEMP output voltage will verify that the LM26 has been assembled properly and that its
temperature sensing circuitry is functional. The VTEMP output has very weak drive capability that can be
overdriven by 1.5mA. Therefore, one can simply force the VTEMP voltage to cause the digital output to change
state, thereby verifying that the comparator and output circuitry function after assembly. Here is a sample test
procedure that can be used to test the LM26CIM5-TPA which has an 85°C trip point.
1. Turn on V+ and measure VTEMP. Then calculate the temperature reading of the LM26 using the equation:
VO = ( - 3.47 ´10 ´(T - 30)2 ) + (1.082´10 ´(T - 30)) + 1.8015 V
or
T = -1525.04 + 2.4182´106 +
-6
-2
(3)
1.8015 - VTEMP
3.479 ´10-6
(4)
2. Verify that the temperature measured in step one is within (±3°C + error of reference temperature sensor) of
the ambient/board temperature. The ambient/board temperature (reference temperature) should be
measured using an extremely accurate calibrated temperature sensor.
3.
(a) Observe that OS is high.
(b) Drive VTEMP to ground.
(c) Observe that OS is now low.
(d) Release the VTEMP pin.
(e) Observe that OS is now high.
4.
(a) Observe that OS is high.
(b) Drive VTEMP voltage down gradually.
(c) When OS goes low, note the VTEMP voltage.
(d) VTEMPTrig = VTEMP at OS trigger (HIGH->LOW)
(e) Calculate Trig using Equation 2.
5.
(a) Gradually raise VTEMP until OS goes HIGH. Note VTEMP
.
(b) Calculate THYST using Equation 2.

9.2.2 Detailed Design Procedure
The design procedure is simple. A fan was selected that has the capability to be controlled by an external NTC
thermistor. The recommended NTC thermistor adjusts the fan speed to maximum at 40°C. The LM26 meets the
threshold accuracy requirements for temperature control of the fan speed and allows setting the max speed
temperature threshold higher as required to 45°C. The resistance of the thermistor for the min fan speed is 6.8
kΩ. Since thermistors have a negative temperature coefficient (NTC), 10 kΩ was chosen to ensure that the fan is
at min speed when the LM26 OS is off. When the OS output goes low at 45°C it simulates the low thermistor
resistance at higher temperatures thus setting fan to max speed.

10 Power Supply Recommendations
The LM26 has excellent power supply noise rejection. Listed below is a variety of signals used to test the LM26
power supply rejection. False triggering of the output was not observed when these signals where coupled into
the V+ pin of the LM26.
•
•
•
square wave 400 kHz, 1 Vp-p
square wave 2 kHz, 200 mVp-p
sine wave 100 Hz to 1 MHz, 200 mVp-p
Testing was done while maintaining the temperature of the LM26 one degree centigrade way from the trip point
with the output not activated.
11 Layout
11.1 Layout Guidelines
The LM26 can be applied easily in the same way as other integrated-circuit temperature sensors. It can be glued
or cemented to a surface. The temperature that the LM26 is sensing will be within about +0.06°C of the surface
temperature to which the LM26's leads are attached to.
This presumes that the ambient air temperature is almost the same as the surface temperature; if the air
temperature were much higher or lower than the surface temperature, the actual temperature measured would
be at an intermediate temperature between the surface temperature and the air temperature.
To ensure good thermal conductivity, the backside of the LM26 die is directly attached to the GND pin (pin 2).
The temperatures of the lands and traces to the other leads of the LM26 will also affect the temperature that is
being sensed.
Alternatively, the LM26 can be mounted inside a sealed-end metal tube, and can then be dipped into a bath or
screwed into a threaded hole in a tank. As with any IC, the LM26 and accompanying wiring and circuits must be
kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold
temperatures where condensation can occur. Printed-circuit coatings and varnishes such as Humiseal and epoxy
paints or dips are often used to ensure that moisture cannot corrode the LM26 or its connections.

11.3 Thermal Considerations
The junction to ambient thermal resistance (RθJA) is the parameter used to calculate the rise of a part's junction
temperature due to its power dissipation. For the LM26 the equation used to calculate the rise in the die junction
temperature is as follows:
TJ = TA + QJA (V+ - VTEMP )IL _ TEMP + VDOIDO
)
where
•
•
•
•
TA is the ambient temperature, V+ is the power supply voltage
IQ is the quiescent current, IL_TEMP is the load current on the VTEMP output
VDO is the voltage on the digital output
and IDO is the load current on the digital output
(5)
Since the LM26's junction temperature is the actual temperature being measured, care should be taken to
minimize the load current that the LM26 is required to drive.
Table 3 summarizes the thermal resistance for different conditions and the rise in die temperature of the LM26
without any loading on VTEMP and a 10-kΩ pullup resistor on an open-drain digital output with a 5.5-V power
supply.

OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

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.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
