INA302和INA303器件具有一个高共模,双向电流传感放大器和两个高速比较器,用于检测超出范围的电流状况.INA302比较器配置为检测和响应过流状况.INA303比较器配置为在窗口配置中响应过流和欠流状况。该器件每个一个可调节限制阈值范围,该范围通过一个外部限值设定电阻进行设置。这些电流分流监控器可在独立于电源的-0.1V至36V共模电压范围内测量差动电压信号。
开漏极警报输出可配置为在透明模式(输出状态)与输入状态保持一致)或运存模式(警报输出在锁存复位时清除)下运行。比较器1的警报响应时间小于1μs,而比较器2的警报响应时间通过外部电容器进行设置,范围介于2μs至10s之间。
此装件由2.7V至5.5V的单个电源供电,消耗的最大电源电流为950μA。该器件具有扩展级工作温度范围( 40℃至+ 125℃),并且采用14引脚TSSOP封装。
