A3949 Description
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.
