Overview
COMPLEMENTARY OUTPUT HALL EFFECT LATCH General Description Features Data Sheet AH277A The AH277A 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, a temperature compensation circuit to compensate the temperature drift of Hall sensitivity and 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.
Placing the device in...
