INA301 由高共模电流感测放大器和高速比较器组成，通过测量电流感测或分流电阻两侧的电压并将该电压与定义的阈值限值作比较来检测过流情况。该器件 具有 一个可调限制阈值范围，此范围由单个外部限值设定电阻器设置。此分流监控器能够在 0V 至 36V 的共模电压范围内测量差分电压信号，并且与电源电压无关。
开漏报警输出可配置为透明模式（输出状态与输入状态保持一致）或锁存模式（复位锁存时清除报警输出）。器件报警响应时间不到 1µs，能够快速检测过流事件。
这款器件由 2.7V-5.5V 单电源供电运行，最大电源电流消耗为 700µA。此器件在扩展级温度范围（-40°C 至 +125°C）下额定运行，并采用 8 引脚 VSSOP 封装。
