Target Application
The TLE4927C E6547 is an active Hall sensor suited to detecting the motion and position of ferromagnetic or permanent magnet targets. An additional self-calibration module is implemented to achieve optimum accuracy during normal running operation. The device comes in a 3-pin package providing pins for the supply voltage and an open drain output. Infineon also offers customers the possibility to purchase sensors with already attached back bias magnets (TLE4927CB E6547).
