Magnetic position sensors, Linear sensors TLE4999C8-S0001
XENSIV™ - TLE4999C8-S0001 programmable dual channel linear Hall sensor in thin 8 pin SMD single sensor package The Infineon TLE4999C8-S0001 is a dual channel linear Hall sensor with a bus-capable digital Short-PWM-Code (SPC) interface. The Infineon TLE4999C8 S-0001 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. The sensor is developed in compliance to ISO 26262 (first edition 2011), supporting safety requirements on system level rated up to ASIL C. The product offers a high magnetic sensitivity drift of 2.5%. Furthermore the noise main channel is 1 LSB12 and sub channel 4 LSB12. Summary of Features Two highly accurate redundant Hall measurement channels (main and sub) integrated on one chip Developed compliant to ISO 26262 (first edition 2011) Safety Element out of Context for safety requirements rated up to ASIL C High diagnostic coverage by plausibility checking of main and sub signal on system level Fast digital SPC interface with min. 0.5µs unit time for transmission of main and sub signals in less than 500 µs Bus-capability for up to 4 sensor ICs on one data line Selectable 12/14/16bit output signals, protected by CRC and rolling counter Thin 8 pin SMD single sensor package Operating automotive temperature range -40°C to 125°C Digital temperature and stress compensation Reverse-polarity and over voltage protection for VDD, GND and OUT pins Main and sub channel programmable independently in EEPROM Multipoint calibration up to 9 points Frameholder mechanism Single-wire SICI programming interface on output pin 2 x 16 bit user-configurable ID in EEPROM Potential Applications Robust replacement of potentiometers: No mechanical abrasion, resistant to humidity, temperature, pollution, and vibration Linear and angular position sensing in automotive and industrial applications with highest accuracy requirements Suited for safety applications such as pedal position, throttle position, and steering torque sensing
