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。

所有功能
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I_RMS = 3 A_rms 和 R_DSon HS + LS = 500 mΩ typ.

待机电流消耗低
