LOW VOLTAGE HALL-EFFECT SMART FAN MOTOR  
CONTROLLER  
Description  
Pin Assignments  
AH293 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. Also, rotor-state  
detection (RD) output is 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.
