AH266 - BCD Semiconductor

AH266 HIGH VOLTAGE HALL EFFECT LATCH

The AH266 is an integrated Hall sensor with output driver designed for electronic commutation of brushless DC motor applications. The device includes an onchip Hall sensor for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection and two complementary darlington open-collector dr.
