BM6209FS
BM6209FS is 3-Phase Brushless Fan Motor Driver manufactured by ROHM.
For Air-Conditioner Fan Motor
3-Phase Brushless Fan Motor Driver
General Description This motor driver IC adopts Presto MOS™ as the output transistor, and put in a small full molding package with the 180° sinusoidal mutation 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.
