GENERAL DESCRIPTION

MA7611 is integrated Hall sensors with output drivers, mainly designed for electronic

commutation of brush-less DC Fan. This IC is using HV BCD process internally includes the

regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary

open-Drain outputs (DO, DOB).

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.
