SERIAL CONTROL H-BRIDGE DRIVER FOR CAMERA LENS DRIVING
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.
FEATURES
• Six H-bridge circuits using power MOSFET
• Motor control using serial data (6 bytes of 8-bit configuration)
