BIPOLAR HALL EFFECT POSITION SENSOR
FSH41
„ GENERAL DESCRIPTION
The FSH41 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor
applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that
amplifiers the Hall voltage, and a Schmitt to provide switching hysteresis for noise rejection, and open-collector output.
An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and
allows a wide operating supply range.
A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF.
