3.1
Functional description
The TLE4999C4-S0001 is a dual channel linear Hall sensor designed to meet the requirements of applications
with highly accurate and reliable magnetic field measurement. The sensor provides a digital SPC (Short PWM
Code) protocol on the OUT pin that is based on the SENT (Single Edge Nibble Transmission) standard.
Configuration parameters can be programmed after assembly of the sensor in a module in an end-of-line
calibration procedure using the serial inspection and configuration interface (SICI).
The two measurement channels have separate analog supply domains controlled by the main and sub analog
regulators. These regulators feed separate biasing units for the main and sub Hall sensor elements.
A multiplexed second analog-digital converter (Sub HTS-ADC) is used to convert analog signals from the main
and sub temperature sensors, and the sub Hall probe. The sub Hall, the temperature and the stress signals are
fed into the second digital signal processing unit (DSP2).
The DSP2 uses the signals from all stress and temperature sensing elements for plausibility and range checks
to ensure the integrity of the sensing elements and the analog signal path.
The analog signal of the main Hall probe is fed into an analog-digital converter (Main HADC), and is then
processed in a digital signal processing unit (DSP1).
Each DSP uses its corresponding Hall signal, together with compensation parameters stored in the EEPROM,
to calculate a Hall measurement value that is compensated for stress and temperature effects.
A high speed SPC protocol is generated containing the data of the two DSPs in the SPC protocol encoder and
transmitted after a SPC trigger pulse.

4) Value valid only when the 3.3V bus capability bit is set in the EEPROM.
5) Output protocol characteristics depend on these parameters, RL must be according to max. output current. For the
maximum output pull up voltage value refer to the note on Table 3.
6) The SPC output protocol will be deactivated when permanent voltages higher then 7.5V are present at the OUT pin.
7) Pull-up resistance and load capacitance have to be chosen in accordance with configured unit time, please see
Application circuit.
6.1
Calculation of the junction temperature
The internal power dissipation PTOT of the sensor increases the chip junction temperature above the ambient
temperature (TA).
The power multiplied by the total thermal resistance RthJA (junction to ambient) added to TA leads to the
final junction temperature. RthJA is the sum of the addition of the two components, Junction to Case and
Case to Ambient.
RthJA=RthJC +RthCA
TJ=TA +Δ T = RthJA xPTOT = RthJA x(VDD x IDD +VOUT x IOUT); IDD, IOUT > 0, if direction is into IC
Example (assuming no load on VOUT ):
• VDD = 5.5 V
• IDD = 14.5mA
• ΔT= 165 [K/W] x (5.5 [V] x 0.0145 [A] + 0 [VA]) = 13.159K → 15K used for worst case scenario calculations

SPC output
The TLE4999C4-S0001 features a fast SPC (Short PWM Code) protocol, which is based on the SENT standard
(Single Edge Nibble Transmission) defined by SAE J2716. As opposed to SENT, which implies a continuous
transmission of data, the SPC protocol transmits data only after receiving a specific trigger pulse from the
micro controller. The required length of the trigger pulse depends if the sensor is configured in synchronous
mode or in bus mode. In case of bus mode the trigger pulse depends on the sensor number, which is
configurable. Thereby, SPC allows the operation of up to four sensors on one bus line.
For the SPC interface the push pull setting with controlled slopes is used (the push-pull mode is only active
during the slope controlled mode). In this configuration, the TLE4999C4-S0001 has controlled rising and
falling slopes. Between the slope controlled transitions the HIGH level is maintained by the external pull-up
resistor. Once the SPC protocol telegram is sent, the TLE4999C4-S0001 goes in to receiving mode (OUT Pin in
Tri-sate mode) and waits until a valid trigger signal is received.

SPC default protocol example
As in the SENT protocol, the time between two consecutive falling edges defines the value of a 4-bit nibble,
thus representing numbers between 0 and 15. The transmission time therefore depends on the transmitted
data values. All values are multiples of a unit time frame (see Table 8). A SPC frame consists of the following
nibbles (see Table 7):
•
•
•
A trigger pulse by the master, which initiates the data transmission.
A synchronization period of 56 UT.
A status nibble of 12-27 UT, containing over voltage/ error signaling and short serial message (SSM) data or
the sensor ID.
•
•
Between 3 and 4 data nibbles of 12-27 UT each (number is programmable), representing the Main Hall

An end pulse of 12 UT to terminate the SPC frame transmission.
The sensor is available for the next sample after the falling edge of the end pulse. The sensor’s sampling
time is at the beginning of the synchronization period, i.e. when a correct trigger is received.

Content of the SPC protocol
8.1
SPC bus mode
When the sensor is used in a bus mode with other sensors on a common SPC line, individual addresses have
to be assigned to each sensor for identification. For the operation of the sensor in a SPC bus mode, it is strongly
recommended that the sensor ID is written into the EEPROM of the sensor, as all sensors are pre configured
with the default value “ID = 0” (see the TLE4999C User Manual for further details).
A corresponding trigger nibble from the micro controller can therefore address each sensor individually.

The trigger nibble low time is shown in Table 10. Each low time corresponds to an individual sensor address.
The total length of the trigger nibble can be selected to be constant at 90 UT (constant trigger length) or

1) Default setting is 3 μs nominal SPC unit time.
8.3
SPC trigger pulse
A SPC transmission is initiated by a trigger pulse from the ECU on the OUT pin. To detect a low-level on the
OUT pin, the voltage has to be below the threshold Vth, falling. The sensor detects that the OUT line has been
released as soon as Vth, rising is crossed. Table 9 and Figure 9 show the timing specification for the trigger pulse.
The master low time tmlow as well as the total trigger time tmtr are different for SPC bus mode on or off. With bus
mode switched off, the total trigger time tmtr is shortest. This leads to a significantly shorter overall protocol
transmission time for configurations where only one sensor IC is connected to the SPC line.
With bus mode switched on, it is possible to use up to four SPC sensors on one data line. The total trigger time
in bus mode is longer, and can be selected between a constant trigger or a variable trigger.
The master low time tmlow is used to identify the sensor ID of the addressed sensor IC, see Table 10. A proper
addressing requires all sensors on the bus to be programmed with the same nominal SPC unit time.

Status nibble
The status nibble consists of 4 bits. The first two bits are status bits to monitor the internal status of the sensor
whereas the last two bits can represent a short serial message (see Chapter 8.5) or the sensor ID. Table 12
shows the usage of the status bits.
The status nibble, which is sent with each SPC data frame, provides an error indication. In case the sensor
detects an error or an over voltage condition, the corresponding error bit in the status nibble is set. As long
as the error or over voltage condition is present the error bit is set and the sensor output is disabled. After
returning from the over voltage condition the corresponding error bit is set in the first transmitted frame in the
status nibble.

Short serial message
The short serial message is an additional option which can be enabled or disabled. The short serial message
provides additional information in a slow channel transmitting an 8 bit temperature value of the main hall and
32 bit sensor ID (16 bits from main channel ID1 and 16 bits from sub channel ID2).
In each SPC frame, one bit of information is transmitted. The start of the short serial message is indicated by
a “1” in bit [1] of the status nibble. For the next 15 SPC frames, this bit will contain a “0”. The Information is
transmitted in blocks of 16 bit with 1 bit per SPC frame in bit [0] of the status nibble.
4 bit message ID
8 bit data
4bit CRC (calculated from message ID and data bits)
The message ID is used for identification of the type of data received. All data are transmitted in the bit [0] of
the status nibble in the order MSB to LSB.
The transmitted information is as follows:
Message -ID 0: 8 bit temperature value starting with MSB
Message -ID 1: 8 bit of sensor ID1 (starting with MSB)
Message -ID 2: 8 bit of sensor ID1 (starting with MSB-8)
Message -ID 3: 8 bit of sensor ID2 (starting with MSB)
Message -ID 4: 8 bit of sensor ID2 (starting with MSB-8)

Temperature nibbles
The temperature is coded as an 8 bit value. The value is transferred in unsigned integer format and
corresponds to the range between -55 °C and +200 °C, so a transferred value of 55 corresponds to 0 °C. The
temperature is additional information and although it is not calibrated, may be used for a plausibility check,
for example. Table 13 shows the mapping between junction temperature and the transmitted value in the
SPC frame.

8.7
Rolling Counter
The rolling counter is an additional option for a safety check implementation. Therefore the counter counts
the number of transmitted frames with rollover back to 0 and increments with each message. The ECU can use
this data for verification that no frame is missed or that no frame is sent repeatedly from the sensor.
There are two selectable protocols that include the rolling counter (see Figure 8), on frame D a 2 bit rolling
counter is included in the first main data nibble and another 2 bit rolling counter in the first sub data nibble.
On frame E a 2 bit rolling counter is included in the CRC nibble, further details can be found in Chapter 8.8.
There are frames without rolling counter bits, but to meet the safety requirements and target ASIL level of the
application, it is recommended to use this function.
8.8
CRC nibble
The CRC checksum can be used to check the validity of the decoded data. In the checksum included is the
status nibble and the data nibbles. It is calculated using a polynomial(x4 + x3 + x2 + 1) with a seed value of 0101B.
The remainder after the last data nibble is transmitted as CRC.
To allow enhanced checksum for higher diagnostic coverage also 6 and 8 bit checksum are available to secure
the data transmission (see Table 7).
The 6 bit checksum is calculated using a polynomial (x6 + x + 1) with a seed value of 010101B and the 8 bit
checksum is calculated using a polynomial (x8 + x5+ x3 + x2 + x + 1) with a seed value of 01010101B.
The calculation scheme of the CRC is described in detail in the TLE4999C User Manual.
8.9
SPC frameholder
The frameholder functionality allows the user to operate multiple sensors in a bus configuration with
synchronized sampling of the measurement value. This is achieved by having (apart from the SPC Bus ID) a
separate frameholder ID for each chip on the bus which is used as a common signal trigger.
