DESCRI PT I ON

UTC UM2640 is a 2-phase pre-driver IC for unipolar DC brushes

motors. It features high voltage bipolar technology so that the driver

works up to 48V. High voltage operation delivers more power and

improves power supply efficiency. Therefore, it is suitable for high

voltage fan motor applications.
