AH293 Low Voltage Hall-Effect Smart Fan Motor Controller Features - On chip Hall sensor - Rotor-locked shutdown - Automatically restart - Rotor-state detection (RD) output - Buil t-in Zener protection for output driver - Operating voltage: 1.8V~5.75 V - Output current: IO( AVE ) = 400 mA - Package: SIP-5L, SOT23-5L, SOT89-5L General Description AH293 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-collector transistors for motor’s coil driving, automatic lock current shutdown, and recovery protections. Besides, rotor-state detection (RD) output is for speed detection. 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. These protecting actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers running normally.
