Overview

A4973 Full-Bridge PWM Motor Driver Features and Benefits ▪ ±1.
5 A continuous output current ▪ 50 V output voltage rating ▪ 3 V to 5.
5 V logic supply voltage ▪ Internal PWM current control ▪ Fast and slow current-decay modes ▪ Sleep (low current consumption) mode ▪ Internal transient-suppression diodes ▪ Internal thermal shutdown circuitry ▪ Crossover current and UVLO protection Description Designed for bidirectional pulse width modulated (PWM) current control of inductive loads, the A4973 is capable of continuous output currents to ±1.
5 A and operating voltages to 50 V.
Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value.
