Datasheet  
For Air-Conditioner Fan Motor  
3-Phase Brushless Fan Motor  
Driver  
BM6249FS  
General Description  
Key Specifications  
This 3-phase Brushless Fan motor driver IC adopts  
PrestoMOSas the output transistor, and put in a small  
full molding package with the 180° sinusoidal  
commutation controller chip and the high voltage gate  
driver chip. The protection circuits for overcurrent,  
overheating, under voltage lock out and the high voltage  
bootstrap diode with current regulation are built-in. It  
provides downsizing the built-in PCB of the motor.
