Overview
...RANSLATOR The A3977xED and A3977xLP are complete microstepping motor drivers with built-in translator.
They are designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 35 V and ±2.
5 A.
The A3977 includes a fixed off-time current regulator that has the ability to operate in slow-, fast-, or mixed-decay modes.
This currentdecay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.
The translator is the key to the easy implementation of the A3977.
By simply inputting one pulse on the STEP input the motor will take one step (full, half, quarter, or eighth depending on two...
