Part Number : AH292
Function : LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER
Manufacturers : Diodes Incorporated.
AH292 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. In addition a Frequency generator (FG) output is also available for speed 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.
The AH292 is available in SOT89-5L package.
