MOS INTEGRATED CIRCUIT

µ PD168111A

MICROSTEP DRIVER FOR DRIVING CAMERA LENS

DESCRIPTION

The µPD168111A is a monolithic 2-channel H bridge driver that consists of a CMOS controller and a MOS output

stage. It can reduce the current consumption and the voltage loss at the output stage compared with a conventional

driver using bipolar transistors, thanks to employment of a MOS process. This product employs a P-channel

MOSFET on the high side of the output stage, eliminating a charge pump. As a result, the circuit current consumption

can be substantially reduced during operation.

This product is ideal for driving the motor of a digital still camera as it can switch over between two-phase

excitation driving and microstep driving, using a stepper motor.

FEATURES

O Two H bridge circuits employing power MOSFET

O Current feedback 64-step microstep driving and two-phase excitation driving selectable

O Motor control by serial data (6 words of 16-bit configuration)

Data is input with the LSB first.

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

O Input logic frequency: 6 MHz MAX.

O 3 V power supply

Minimum operating power supply voltage V^DD= 2.7 V

O Undervoltage lockout circuit

Shuts down internal circuitry at V^DD= 1.7 V TYP.

O Constrained output leak current

Built-in the shut off circuit of V^Mpin output leak current at V^DD= 0 V.

O 24-pin TSSOP
