? ?The OCH149 is an integrated Hall effect latched
sensor designed for electronic commutation of
b-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.?
