General Information

The TLE4925/TLE4925C is an active Hall sensor suited to detects the motion and

position of ferromagnetic and permanent magnet structures. An additional self-

calibration module has been implemented to achieve optimum accuracy during normal

running operation. It comes in a three-pin package for the supply voltage and an open

drain output.

Functional Description

The differential Hall sensor IC detects the motion and position of ferromagnetic and

permanent magnet structures by measuring the differential flux density of the magnetic

field. To detect ferromagnetic objects the magnetic field must be provided by a back

biasing permanent magnet (south or north pole of the magnet attached to the rear

unmarked side of the IC package).
