◼ General Description
The OCH41H 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 south pole of sufficient strength will turn the output ON.
In the absence of a magnetic field, the output is OFF.
