TLE4999C4 Overview
The TLE4999C4 is a dual channel linear Hall sensor with a bus-capable digital Short-PWM-Code (SPC) interface. Both channels are integrated on one die in the chip. The highly accurate measurement channels (main and sub) can be used for a plausibility check on system level.
TLE4999C4 Key Features
- Two highly accurate redundant Hall measurement channels (main and sub) integrated on one chip
- Developed pliant to ISO 26262 (first edition 2011) Safety Element out of Context for safety requirements rated up to ASI
- 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 4 pin leaded single sensor package
- Operating automotive temperature range -40°C to 150°C
- Digital temperature and stress pensation
- Reverse-polarity and over voltage protection for VDD, GND and OUT pins
TLE4999C4 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
