Applications

The TLE4955C is an integrated differential Hall effect sensor for transmission applications with two wire PWM

output current interface. Its basic function is to provide information about rotational speed and direction of

rotation to the transmission control unit. TLE4955C includes a sophisticated algorithm which actively

suppresses vibration while keeping excellent air gap performance.

Description

1) Magnetic parameters are valid and characterized for f > 1 Hz

2) Value of capacitor: 1.8 nF +/-10% (excluded drift because of temperature and over lifetime); ceramic: X8R; maximum voltage: 50 V.
