Description
AH291 is a monolithic fan motor controller with Hall sensor’s capability. It contains two complementary open-collector drivers for motor’s coil driving,automatic lock shutdown and restart function relatively. 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 AH291 is available in SIP4 and SOT89-5L packages.

Features
•  On Chip Hall Sensor
• Rotor-Locked Shutdown
• Automatically Restart
•  Built-in Zener Protection for Output Driver
•  Operating Voltage: 1.8V to 5.75V
•  Output Current: IO(AVE)= 400mA
•  Packages: SIP-4L and SOT89-5L
•  Green Molding Compound
