Description

Top Features

A5950 设计用于直流电机脉宽调制 (PWM) 控制，峰值电流输出高达 ±3 A，工作电压高达 40 V。

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。

A5950 采用扁平 4 mm × 4 mm 16 管脚 QFN 封装（后缀“EU”），并提供可沾锡侧翼选项（后缀“-P”），或 16 管脚 eTSSOP（后缀“LP”），所有三种型号带外露电源板以增强散热。
