BM6204FS Datasheet - ROHM

BM6204FS 3-Phase Brushless Fan Motor Driver

This motor driver IC adopts PrestoMOS™ as the output transistor, and put in a small full molding package with the 120° square wave commutation controller chip and the high voltage gate driver chip. The protection circuits for overcurrent, overheating, under voltage lock out and the high voltage boot.
