MOS INTEGRATED CIRCUIT
µPD168110
MICROSTEP DRIVER FOR DRIVING CAMERA LENS
DESCRIPTION
The µPD168110 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.
