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.
