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).
