General Description

The A4992 is a flexible microstepping motor driver with integrated phase current control and a built-in translator for easy operation.

It is a single chip solution designed to operate bipolar stepper motors in full, half, quarter, eighth, and sixteenth step modes, at up to 28 V.

At power-on, the A4992 is configured to drive most small stepper motors with simple step and direction inputs.
