TLE4999C8XUMA1

TLE4999C8XUMA1 is a programmable dual-channel linear hall single sensor with a fast SPC interface. 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 the system level. This enables a high diagnostic coverage. The sensor is developed in compliance to ISO 26262 (first edition 2011), supporting safety requirements on system level rated up to ASIL D. Highest accuracy over a wide temperature range and lifetime is achieved by an integrated digital temperature- and stress-compensation. Ideal for 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.
