For air-conditioner fan motor
3-Phase Brushless Fan Motor
Driver
BM6203FS
General Description
This motor driver IC adopts PrestoMOS™ as the output
transistor, and put in a small full molding package with
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 for a
wide variety of applications by the combination with
controller BD6201X series and enables motor unit
standardization.
Features
600V PrestoMOS™ built-in
Output current 2.5A
Bootstrap operation by floating high side driver
(including diode)
3.3V logic input compatible
Protection circuits provided: OCP, TSD and UVLO
Fault output (open drain)
Applications
Air conditioners; air cleaners; water pumps;
dishwashers; washing machines
