AH477A Description
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 parator to provide switching hysteresis for noise rejection, a bi-directional drivers for sinking and driving large current load. It also includes an internal bandgap regulator to provide...
