A3950SLPTR-T

Preliminary Data Sheet Subject to Change without Notice November 4, 2005 A3950 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-to-supply / short-toground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection. The A3950 is supplied in a thin profile (
