PRE-DRIVER IC
„ 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.
* Lock Alarm Output Terminal
