Product Summary
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.
