Microstepping DMOS Driver With Translator

The A3979 is a complete microstepping Motor Driver with built-in translator, designed as a pin-compatible replacement for the successful A3977 with enhanced microstepping (1/16 step) precision. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes, with an output drive capacity of up to 35 V and 2.5 A. The A3979 includes a fixed off-time current Regulator that has the ability to operate in Slow, Fast, or Mixed decay modes. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.
