Stepper Motor Driver AD1231

YA7159-1/3

- 2 -

2. Features

AD1231 is a constant current stepper motor driver of 2 phase unipolar type.

- It drives a unipolar motor with bifilar coil windings.

- Output current can be set by a rotary switch easily.

- It has auto current down function to prevent heat generation during the motor stopping.

- Excitation method can be selected from 2-phase to 4W1-2 phase excitation by a switch. It can drive a

motor with low vibration.

- It fits for an experiment or evaluation as well as for being embedded in devices.
