Datasheet
For Air-Conditioner Fan Motor
3-Phase Brushless Fan Motor
Driver
BM6248FS
General Description
This 3-phase Brushless Fan motor driver IC adopts
PrestoMOSas 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 downsizing the built-in PCB of the motor.
Features
600V PrestoMOS™ Built-in
Output Current 1.5A
Bootstrap operation by floating high side driver
(including diode)
180° Sinusoidal Commutation Logic
PWM Control (Upper and lower arm switching)
Phase control supported from 0° to +40° at 1° intervals
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
