  • STSPIN840是一款紧凑型直流有刷电机驱动器,能够同时驱动两个双向直流有刷电机。它采用非常小的4 x 4 mm QFN封装,集成了控制逻辑和完善保护的低RDSon 双全桥功率级。

    借助专用的PARALLEL输入引脚,可以启用并行模式功能,将器件转换为等效且功能更强大的单个全桥,能够以500 mΩ的等效HS + LS RDSon提供高达 3Arms 的电流。
    STSPIN840基于用户设置的参考电压和关断时间值,嵌入两个独立的PWM电流控制器(每个全桥一个)。
    可以强制器件处于低功耗状态,从而将总电流消耗降低45μA以下。
    与STSPIN系列的所有其他器件一样,STSPIN840集成了一整套功率级保护(非耗散性过流,热关断,短路和欠压锁定),使其成为新一波高要求工业应用的解决方案。

    主要特性

    • 工作电压为7至45 V
    • 最大输出电流1.5 Arms
    • RDSon(HS) + LS = 1 Ω(典型值)
    • 可调OFF时间的电流控制
    • 基于外部电阻的电流检测
    • 全面保护措施
      • 无损过流保护
      • 短路保护
      • 欠压锁定
      • 热关机
    • 并联运行模式实现单全桥配置,输出IRMS = 3 Arms 和 RDSon HS + LS = 500 mΩ typ.
    • 待机电流消耗低
