Applications
The TLE4955C-E4 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-E4 includes a sophisticated algorithm which
actively suppresses vibration while keeping excellent air gap performance.
