TLE4999I3
Programmable Dual Channel Linear Hall Sensor with PSI5 Interface
Functional Description
3
Functional Description
The TLE4999I3 is a dual channel linear Hall sensor designed to meet the requirements of highly accurate
steering torque measurement applications. The sensor provides a digital Manchester-encoded current
modulation signal that is compatible to PSI5 v2.1 on the PSI5 pin. Configuration parameters can be
programmed after assembly of the sensor in a module in an end-of-line calibration procedure using the two-
wire SICI (serial inspection and configuration interface).
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. 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). A multiplexed second analog-digital converter (sub HTS-ADC) is used to
convert analog signals from the main and sub temperature and stress sensing elements, and the sub Hall
probe. The sub Hall, sub temperature and sub stress signals are fed into the second digital signal processing
unit (DSP2). The main temperature and main stress signals are fed into DSP1. Each DSP uses its corresponding
temperature, stress and Hall signal, together with compensation parameters stored in the EEPROM to
calculate a Hall measurement value that is compensated for stress and temperature drift effects.
A high speed Manchester-encoded protocol is generated from the data of the two DSPs in the PSI5 output
stage. The protocol is transmitted in synchronous mode, triggered by a synchronization pulse on the PSI5 pin.

Digital Current Interface
The TLE4999I3 has a digital current interface in synchronous mode, which is compatible to PSI5 Rev2.1.
8.1
Manchester Encoding
The digital interface uses Manchester encoding for data transmission. In the middle of each bit there is a rising
or falling edge, which is interpreted as a logical “0” or “1” by the receiver (see Figure 5). This allows for a
synchronisation of the receiver to the sensor and efficient bit-error detection.

Communication Protocol
The communication frame format of the TLE4999I3 is P10P-400/4H, with a bit rate of 189 kbps. After receiving
a valid sync pulse, the sensor transmits four 10bit data messages, which contain the two measurement values
of the main and sub channel, message counter and CRC checksum. Each message has two start bits and one
parity bit.
The digital protocol has one common 7bit checksum that is calculated from all four messages.

Digital Interface timing
After the sync pulse is received by the TLE4999I3, it sends the first data frame after the response time tPD, which
is measured from the beginning of the sync pulse (see Figure 7). The TLE4999I3 outputs four data frames with
a gap of tgap between the frames.
