Allegro MicroSystems - A4952, A4953: 全桥式 DMOS PWM 电动机驱动器 - yaboAPP亚博,yabo亚博网站,亚博电竞官网客户端

Description

设计用于直流电动机的 PWM（脉宽调制）控制，A4952 和 A4953 能够承受峰值输出电流达 ±2 安培，峰值工作电压达到 40 伏特。

该产品可提供输入端子，通过外部施加的 PWM 控制信号控制直流电动机的速度与方向。采用内部同步整流控制电路降低脉宽调制 (PWM) 操作时的功率消耗。

内部电路保护包括过电流保护、电动机接地或电源短路、因滞后引起的过热关机、VBB 欠压监视以及交叉电流保护。

A4952 提供超薄 10 针 MSOP 封装，A4953 提供超薄 8 针 SOICN 封装。两种封装都具有外露焊盘，以提高散热功能，且均是无铅产品，引脚框采用 100% 雾锡电镀。
