BD61250MUV
Multifunction Single-phase Full-wave Fan Motor Driver

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.
