A4956 Datasheet (Allegro) - Full-Bridge PWM Gate Driver

A4956, Full-Bridge PWM Gate Driver

Designed for pulse-width-modulated (PWM) control of DC motors, the A4956 is capable of 50 V operation and provides gate drive for an all N-channel external MOSFET bridge.

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