A3950 Datasheet PDF - Allegro MicroSystems

DMOS Full-Bridge Motor Driver

●Designed for PWM (pulse width modulated) control of dc motors, the A3950 is capable of peak output currents to ±2.8 A and operating voltages to 36 V.

●PHASE and ENABLE input terminals are provided for use in control ling 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.
