OCH149
60V High Voltage Bipolar Hall Effect Position Sensor
General Description
The OCH149 is an integrated Hall effect latched
sensor designed for electronic commutation of
brush-less high-voltage high-power 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 an 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.
The internal filter and protection block can keep the
output voltage at safety level and avoid the damage
of the sensors.
Features
Wide operating voltage range: 3.8V~60V
ESD:HBM-8KV;MM-800V
Wide operating temperature range: -40°C~+150°C
