| AH288 High Voltage Hall-Effect Smart Fan Motor Controller Features - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Frequency generator (FG) output - Buil t-in Zener protection for output driver - Operating voltage: 3.8V~28V - Output current: IO(AVE) = 400mA - Package: SIP-5L, SOT89-5L General Description AH288 is a monolithic fan motor controller with Hall sensor's capability. It contains two complementary open-drain transistors as motor coil drivers, automatic lock current shutdown, and recovery protections. Additional, frequency generator (FG) output is for speed detection relatively. 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 the rotor is blocked. Until the blocking is removed, the motor recovers running normally.
