OCH1440
Bipolar Hall Effect Position Sensor
◼ General Description
The OCH1440 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 and integrated the pull-up resistor.
An internal bandgap
regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
To minimize the BOM cost, only one external component is needed to complete the application...
