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.
