It is designed to operate bipolar stepper motors in full-, half-, eighth-, and sixteenth-step modes, at up to 35 V and ±1 A. The A3980 includes a fixed off-time current regulator which has the ability to operate in slow, fast, or mixed decay modes. This results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. The translator is the key to the easy implementation of the A3980....
