A3950SLP-T集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

A3950SLP-T屬于集成電路（IC）的電機驅動器控制器。由Allegro MicroSystems制造生產的A3950SLP-T電機驅動器，控制器產品屬于電機驅動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關機電執(zhí)行器的電源。所實現的具體功能和特性集根據預期負載和預期應用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。

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.
