OCH140
Bipolar Hall Effect Position Sensor
General Description
The OCH140 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.
Features
Wide operating voltage range: 3.0V~24V
Wide operating temperature range: -40°C ~+125°C
Maximum output sink current 25mA
Package: SIP3, TSOT23-3L, SOT89-3L and SOT23-3L
