DESCRIPTION
UTC UH288F(FG)/UH288R(RD) are integrated Hall sensors with output drivers, mainly designed for electronic commutation of brush-less DC Fan. 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.●
