Pin definition and Function
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).
Offset cancellation is achieved by advanced digital signal processing.
Immediately after power-on motion is detected (start-up mode). After a few
transitions the sensor has finished self-calibration and switches to a high-
accuracy mode (running mode). In running mode switching occurs at signal zero-
crossing of the arithmetic mean of max and min value of magnetic differential
signal. ∆B is defined as difference between hall plate 1 and hall plate 2.
