A3949SLB-T Datasheet PDF - Allegro MicroSystems

Designed for PWM (pulse width modulated) control of dc motors, the A3949 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 controlling the speed and direction of a dc motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to reduce power dissipation during PWM operation.

FEATURES
