DESCRIPTION

The μPD168112 is a monolithic 6-channel H-bridge driver that consists of a CMOS controller and a MOS output stage. Compared with existing drivers that use bipolar transistors, this H-bridge driver can lower the current consumption and voltage loss at the output stage thanks to employment of a MOS process. This product employs a P-channel MOSFET on the high side of the output stage, eliminating the need for a charge pump, so that the circuit current consumption can be substantially reduced during operation.

In the μPD168112 driving a stepper motor, DC motor, or coil can be selected by serial control, making this product ideal for driving the motor of a digital still camera.
