OCH41HX
Bipolar Hall Effect Position Sensor
General Description
The OCH41HX 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 trigger 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.
