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 circuit.
