AH286I-YLA

AH286 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: 3.8V~20 V - Output current: IO(AVE) = 500mA for SIP-5/SOT89-5 - Output current: IO(AVE) = 400mA for SOT23-5 - Package: SIP-5L, SOT23-5L, SOT89-5L General Description AH286 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-drain transistors for motor’s coil driving, automatic lock current shutdown, and recovery protections. In addition, rotor-state detection (RD) output is for Rotor-state 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. This function repeats while the rotor is blocked. Until the blocking is removed, the motor recovers running normally.
