AH477A Datasheet - BCD Semiconductor

AH477A SINGLE PHASE HALL EFFECT LATCH

The AH477A is an integrated Hall sensor with Hbridged output driver designed for brushless DC motor applications. The device includes an on-chip Hall sensor for magnetic sensing, an amplifier that amplifies the Hall voltage, a comparator to provide switching hysteresis for noise rejection, a bi-dire.
