TWO PHASE HALL EFFECT LATCH WITH FG OUTPUT

The AH211 is an integrated Hall Sensor with output driver and frequency generator designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall Sensor for magnetic sensing, an Amplifier that amplifies the Hall voltage, a Schmitt Trigger to provide switching hysteresis for noise rejection, a temperature compensation circuit to compensate the temperature drift of Hall sensitivity, two complementary open-collector drivers for sinking large load current. It also includes an internal band-gap Regulator which is used to provide bias voltage for internal circuits. By BCD Semiconductor Manufacturing Limited
