General

3.1 Functional description

The TLE4999C8 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.
