DESCRIPTION

The µPD16886 is a monolithic H bridge driver LSI that employs N-channel MOSFETs in its output stage. This IC incorporates a 1.5-channel H bridge circuit and can control two motors that do not operate at the same time. In addition, forward/reverse, brake, and stop functions are available, making this LSI ideal for driving motors such as the motor for winding the camera film and the lens zoom motor.
