UM2640

DESCRIPTION 

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. 

FEATURES 

* Wide supply voltage range of 4V~55V

* Absolute Maximum Voltage 60V 

* Lock protection 

Auto-restart when the motor lock is undone
