The A3977 is a complete microstepping motor driver with built-in translator. It is designed for the operation of bipolar stepper motors
Stepper motors in full, half, quarter and eighth step operation with an output voltage of 35 V and ±2.5 A. The A3977 contains a current controller with a fixed switch-off time, which can operate in slow, fast or mixed decay mode. This current decay control
reduces audible motor noise, increases step accuracy and reduces power loss.
The translator is the key to the simple implementation of the A3977.
