AH287  
HIGH VOLTAGE HALL-EFFECT SMART FAN MOTOR  
CONTROLLER  
General Description  
Features  
AH287 is a monolithic fan motor controller with Hall sensor’s  
capability. It contains two complementary open-drain drivers for  
motor’s coil driving, automatic lock shutdown and restart function  
relatively.  
On Chip Hall Sensor  
Rotor-Locked Shutdown  
Automatically Restart  
Built-in Zener Protection for Output Driver  
Operating Voltage: 3.8V~28V  
Output Current: IO(AVE) = 400mA  
Lead Free Packages: SIP-4L and SOT89-5L (Note 1)  
SIP-4L and SOT89-5L: Available in “Green” Molding  
Compound (No Br, Sb)  
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.  
Lead Free Finish/ RoHS Compliant (Note 2)

Note: The optional Capacitor C1 and Diode D3 are for power stabilization. C1 is recommended to be E-Cap., luF/25V;  
D3 is recommended to be Zener Diode, VZ =27V. Which C1and D3 value need to be fine tuned to optimize  
design for different coils and power suppliers.
