A3973 Features

* ▪ ±1 A, 35 V Continuous Output Rating ▪ Low RDS(on) DMOS Output Drivers ▪ Optimized Microstepping via 6-Bit Linear DACs ▪ Programmable Mixed, Fast, and Slow Current Decay Modes ▪ 4 MHz Internal Oscillator for Digital Timing ▪ Serial-Interface Controls Chip Functions ▪ Synchronous Rectification for L

A3973 General Description

Designed for pulse-width modulated (PWM) current control of bipolar microstepping stepper motors, the A3973 is capable of continuous output currents to ±1 A and operating voltages to 35 V. Internal fixed off-time PWM current-control timing circuitry can be programmed via a serial interface to opera.
