Allegro MicroSystems - A4956 全桥式 PWM 门驱动器 - yaboAPP亚博,yabo亚博网站,亚博电竞官网客户端

Description

A4956 设计用于直流电动机的脉宽调制 (PWM) 控制，可以以 50 V 电压运行，并为所有 n 通道外部 MOSFET 桥提供门驱动器。

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。

内部电流保护包括 VDS 保护、滞后过热关机、VBB 欠压监视及交叉电流保护。

A4956 器件采用低厚度 4x4 mm 20 触点 QFN 封装（后缀“ES”）以及 20 引脚 eTSSOP （后缀“LP”），均带有外露隔热盘。
