MOS INTEGRATED CIRCUIT
PD168110
MICROSTEP DRIVER FOR DRIVING CAMERA LENS
DESCRIPTION
The PD168110 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 Low on-resistance: 2 Ω MAX.
O 3 V power supply
Minimum operating power supply voltage VDD = 2.7 V
O Under voltage lockout circuit
Shuts down internal circuitry at VDD = 1.7 V TYP.
O 24-pin TSSOP

The horizontal axis indicates the number of steps. This figure shows an example in the CW mode. The pulse advances in synchronization with the rising edge of CLK. The current flows into ch 1 and ch 2 in the positive direction when it flows from OUT1A to OUT1B, and in the negative direction when it flows from OUT1B to OUT1A (the values shown above are ideal values and do not indicate the actual values).
