A3980 is a complete microstepping motor driver with translator from Allegro company. It supports full-, half-, eighth-, and sixteenth-step modes, at up to 35 V and ±1 A. It also 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 A3980 is a complete microstepping motor driver with a built-in translator designed for easy operation of bipolar stepper motors. It supports full-, half-, eighth-, and sixteenth-step modes at voltages up to 35 V and currents up to 1 A. The device includes a fixed off-time current regulator capable of slow, fast, or mixed decay modes to reduce audible noise and power dissipation.
