Product Summary

The A3950SLPTR-T is a DMOS full-bridge motor driver. The A3950SLPTR-T 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 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.
