A3953 Datasheet (Allegro MicroSystems) - Full-Bridge PWM Motor Driver

A3953, Full-Bridge PWM Motor Driver

Designed for bidirectional pulse width modulated (PWM) current control of inductive loads, the A3953 is capable of continuous output currents to ±1.3 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
