双路全桥式 DMOS PWM 电动机驱动器

通过脉宽调制 (PWM) 控制两个直流电动机，A4954 能够承受峰值输出电流达 ±2  安培，并使电压达到 40  伏特。\n\n输入端通过应用外部 PWM 控制信号以控制直流电动机的速度与方向。内部同步整流控制电路用来降低脉宽调制 (PWM) 操作时的功率消耗。\n\n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。\n\nA4954 采用带有外置散热板的 16 引脚 TSSOP 小型封装（后缀 LP）。该封装为无铅封装，且引脚框采用 100% 雾锡电镀。 • 低 RDS(on) 输出 \n• 过电流保护 (OCP) • 电动机短路保护 \n• 电动机引脚接地短路保护 \n• 电动机引脚电池短路保护 \n\n• 低功耗待机模式 \n• 可调 PWM 电流限制 \n• 同步整流 \n• 内部欠压锁定 (UVLO) \n• 交叉电流保护 ;
