Summary
Dual DMOS Full-Bridge Microstepping PWM Motor Driver
Description
Designed for pulse-width modulated (PWM) current control of bipolar microstepping stepper motors, the A3972 is capable of continuous output currents to ±1.5 A and operating voltages to 50 V. Internal fixed off-time PWM current-control timing circuitry can be programmed via a serial interface to operate in slow, fast, and mixed current-decay modes.
