A4950 Datasheet Full-bridge Dmos Pwm Motor Driver

Manufacturer: Allegro MicroSystems

Overview: A4950 Full-Bridge DMOS PWM Motor Driver.

General Description

Designed for pulse width modulated (PWM) control of DC motors, the A4950 is capable of peak output currents to ±3.5 A and operating voltages to 40 V.

Input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals.

Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation.
