产品概述

描述

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R_DSon 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 R_DSon提供高达 3A_rms 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。
