A3972SB is a dual DMOS full-bridge micro-stepping PWM motor driver designed for pulse-width modulated (PWM) current control of bipolar microstepping stepper motors. It is capable of continuous output currents to ±1.5 A and operating voltages to 50 V.
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.
