AH285  
Hall-Effect Smart Fan Motor Controller  
„ Features  
„ General Description  
- On chip Hall sensor  
AH285 is a monolithic fan motor controller with Hall  
sensor’s capability. It contains two complementary  
open-drain transistors as motor coil drivers,  
automatic lock current shutdown, and recovery  
protections. Additional, frequency generator (FG)  
output is for speed detection relatively.  
- Rotor-locked shutdown  
- Automatically restart  
- Frequency generator (FG) output  
- Built-in Zener protection for output driver  
- Operating voltage: 3.8V~20V  
- Output current: IO(AVE) = 500mA for SIP-5/SOT89-5  
- Output current: IO(AVE) = 400mA for SOT23-5  
- Package: SIP-5L, SOT23-5L, SOT89-5L  
To avoid coil burning, rotor-lock shutdown detection  
circuit shut down the output driver if the rotor is  
blocked and then the automatic recovery circuit will  
try to restart the motor. This function repeats while  
the rotor is blocked. Until the blocking is removed,  
the motor recovers running normally.
