The Infineon TLE4999C4 provides all means that are necessary to fulfill the state-of-the-art functional safety requirements on system level. It is developed in full compliance with ISO 26262. The device provides high redundancy on one chip by means of two sensor elements included within one monolithic silicon design. The two diverse Hall sensor elements („main” and „sub”) have internally separated signal paths within the chip. A plausibility check secures the high diagnostic coverage required for premium functional safety compliant systems up to ASIL D.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.The sensor provides 4 different output signal modes (12/14/16bit), protected by CRC and a rolling counter. 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.
