Product Summary

The A3980KLP is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, eighth-, and sixteenthstep modes, at up to 35 V and ±1 A. The A3980KLP 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 A3980KLP. Simply inputting one pulse on the step input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. The A3980KLP interface is an ideal fit for applications where a complex μP is unavailable or overburdened.
