GENERAL DESCRIPTION
The MA7140 is an integrated Hall sensor with H-Bridged 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 comparator to provide switching
hysteresis for noise rejection, a bi-directional drivers for sinking and driving large current
load.
To avoid coil burning, rotor-lock shutdown detection circuit shut down the output driver if
the rotor is blocked and then the automatic recovery circuit will try to restart the motor. This
function repeats while rotor is blocked. Until the blocking is removed, the motor recovers
running normally.
