AH292

AH292 LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR CONTROLLER Features On Chip Hall Sensor Rotor-Locked Shutdown Automatically Restart Frequency Generator (FG) Output Built-in Zener Protection for Output Driver Operating Voltage: 1.8V~5.75 V Output Current: IO( AVE ) = 400 mA Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) Lead Free Packages: SOT89-5L General Description 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.
