Technical content
XENSIV™ magnetic position sensors – world’s first fully ISO 26262 compliant linear Hall sensor for high precision applications Infineon’s new TLE4999I3 is a dual channel linear Hall sensor designed to meet the requirements of safety critical automotive and industrial applications. It is developed in full compliance with ISO 26262 by means of two sensor elements included within one monolithic silicon design. In order to ensure diversity, the sensor cells are designed in a complementary way. Their signals follow two independent analog paths. Each signal path has its own digital signal processing unit to ensure maximum independency – redundancy, respectively. Our XENSIV™ TLE4999I3 provides all measures that are necessary to fulfill the state-of-the-art safety requirements on system level and furthermore enables for ASIL-D system developments › Separate analog supply domains controlled by two regulators feed independent biasing units for the main and sub Hall sensor elements › Two analog-digital converters ensure the separation of the sensor signals › The integrated digital signal processors use dedicated temperature and stress parame- ters-stored in separated EEPROM areas – for compensation of their assigned Hall sensor signals to minimize these effects › The digital protocol contains a common 7-bit checksum ensuring error-free data transmission Simplified block diagram TLE4999I3 › Fully ISO 26262 compliant, supports ASIL-D systems › < 2 % sensitivity drift, < 100 µT offset drift over temperature and life time specification › Integrated digital temperature- and stress-compensation › Fast communication protocol com- plies with PSI5 v2.1 with a bit rate of 189 kbps › High diagnostic coverage, ISO 26262-compliancy and dual sensor cell integration enable for ASIL-D system development › PSI5 interface saves wiring and improves EMC behavior › SSO-3 package enables for flexible ad- aptation outside printed circuit boards › Automotive safety critical applications › Linear movement position sensing – Electric Power Steering (EPS) – Pedal position – Electrical throttle control › Industrial safety applications Key features Key benefits Key applications www.infineon.com/linear-hall CBUF Sub ADC Main ADC Supply Sub analog regulator Digital regulatorMain analog regulator PSI5 output Sub bias ROM 2 ROM 1 Sub T-sensing element Sub S-sensing element A Sub Hall DSP 2 D A DSP 1 D GND PSI5 Main bias EEPROM Interface Main T-sensing element Main S-sensing element Main Hall
