For Air-Conditioner Fan Motor

3-Phase Brushless Fan Motor

Driver

BM6209FS

General Description

This motor driver IC adopts PrestoMOS™ as 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 optimum motor drive system and

downsizing the built-in PCB of the motor.
