BM6213FS Datasheet, PDF (1/31 Pages) Rohm – 3-Phase Brushless Fan Motor Driver

For Air-Conditioner Fan Motor
3-Phase Brushless Fan Motor
Driver
BM6213FS
General Description
This motor driver IC adopts MOSFET as output, 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.
Features
 250V MOSFET built-in
 Output current 2.0A
 Bootstrap operation by floating high side driver
(including diode)
 120° square wave commutation logic
 PWM control
