BM6204FS Datasheet, PDF (1/31 Pages) Rohm – 3-Phase Brushless Fan Motor Driver

For Air-Conditioner Fan Motor
3-Phase Brushless Fan Motor
Driver
BM6204FS
General Description
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 bootstrap diode with current regulation
are built-in. It provides optimum motor drive system and
downsizing the built-in PCB of the motor.
