3-Phase Brushless Fan Motor  
Driver  
BM6244FS  
General Description  
Key Specifications  
This 3-phase Brushless Fan motor driver IC adopts  
MOSFET as the output transistor, and put in a small full  
molding package with the 150°/120° 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.
