GENERAL DESCRIPTION
The MA477K is an integrated Hall sensor with H-Bridged output driver designed for
brushless DC motor applications. The device is using HV BCD process 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-directional drivers for sinking and driving
large current load.
Placing the device in a variable magnetic field, if the magnetic flux density is larger than
threshold BOP, the DO is turned to sink and DOB is turned to drive. This output state is held
until the magnetic flux density reverses and falls below BRP, then causes DO to be turned to
drive and DOB turned to sink.
