Functional Description

T H E D I F F E R E N T I A L Hall sensor IC detects the motion of

ferromagnetic and permanent magnet structures by measuring the

differential flux density of the magnetic field. To detect the motion of

ferromagnetic objects the magnetic field must be provided by a back

biasing permanent magnet. Magnetic and device offsets are cancelled by a

self-calibration algorithm whithin a few transitions. The ON and OFF state

of the IC are indicated by High and Low current consumption.
