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 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.
Internal Circuit Protection includes motor lead short-tosupply / short-to-ground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection.
