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
Rotational direction switch
FG signal output with pulse number switch (4 or 12)
VREG output (5V/30mA)
Protection circuits provided: CL, OCP, TSD, UVLO,
MLP and the external fault input
Fault output (open drain)
Applications
Air conditioners; air purifiers; water pumps;
dishwashers; washing machines
