TLE4959C FX Flexible Transmission Speed Sensor Features Hall based differential speed sensor High magnetic sensitivity Large operating airgap Dynamic self-calibration principle Adaptive hysteresis Output protocols with and without direction of rotation detection High vibration suppression capabilities Three wire voltage interface Magnetic encoder and ferromagnetic wheel application High immunity against ESD, EMC and mechanical stress, improved voltage dropout capability Automotive operating temperature range End-of-line programmable to adjust transmission requirements. Green Product (RoHS compliant) AEC Qualified Applications The TLE4959C FX is an integrated differential Hall speed sensor ideally suited for transmission applications. Its basic function is to provide information about rotational speed and direction of rotation to the transmission control unit. TLE4959C FX includes a sophisticated algorithm which actively suppresses vibration while keeping excellent airgap performance.

It has two integrated capacitors on the lead frame (220 nF/1.8 nF). These capacitors increase the EMC robustness of the device. In 12V applications it is further recommended to use a serial resistor R of 100 (tbd) for Supply protection on the supply line. A pull-up resistor R is mandatory on the output pin and determines the Load maximum current flowing through the output transistor. A value of 1.2k is recommended for the 5V application.
