HALL-EFFECT SMART FAN MOTOR CONTROLLER
Features
On chip Hall sensor Rotor-locked shutdown Automatically restart Rotor-state detection (RD) output Built-in Zener protection for output driver Operating voltage: 3.8V~20 V Output current: IO(AVE) = 500mA for SOT89-5L Lead Free Packages: SIP-5L and 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. Rotor-lock shutdown detection circuit turns off the output driver when the rotor is blocked to avoid coil overheat. Then, the automatic recovery circuit will restart the motor. These protected actions are repeated and periodic during the blocked period. Until the blocking is removed, the motor recovers and runs normally.
