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)

Data is input MSB first.

Pulse cycle, number of pulses, and output current value can be set.

• Input logic frequency: 6 MHz MAX.

• 3 V power supply

Minimum operating power supply voltage: VDD = 2.7 V

• Undervoltage lockout circuit

Shuts down the internal circuit at VDD = 1.7 V TYP.

• 48-pin WQFN
