A4982 Overview
The A4982 is a plete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenthstep modes, with an output drive capacity of up to 35 V and ±2 A. The A4982 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.
