A3950SLP-T集成电路（IC）的电机驱动器控制器规格书PDF中文资料

A3950SLP-T属于集成电路（IC）的电机驱动器控制器。由Allegro MicroSystems制造生产的A3950SLP-T电机驱动器，控制器产品属于电机驱动器和控制器电源管理集成电路 (PMIC) 系列，可用于控制或操作从某电源施加到电机或相关机电执行器的电源。所实现的具体功能和特性集根据预期负载和预期应用的特性有很大差异，范围从用于有刷电机的简单开环速度控制到基于步进电机的高级闭环运动控制。

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 control ling 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.
