Fan Motor Driver
BD61250MUV
General Description
BD61250MUV is pre-driver IC to drive single phase H bridge output composed of external MOS FET.
The power supply input terminal and the drive output have voltage rating of 40V, so it can be used in a 24V power supply
without using voltage drop down circuit.
Features
Pre driver for external power MOS FET
Speed controllable by PWM / DC voltage
Minimum output duty limit
Input / output duty slope adjustment
Silent drive by the PWM soft switching
Lead angle setting
Soft start
Standby mode
Current limit
Lock protection and automatic restart
Rotation speed pulse signal(FG), Lock alarm
signal(AL) selectable
Drive PWM frequency selectable (50kHz/25kHz)
Application
General consumer equipment of Desktop PC, Server,
etc.
Office equipment, Copier, FAX, Laser Printer, etc.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
