说明

INA300 为过电流保护应用而设计,是一个电流检测比较器,通过测量分流电阻器上形成的电压,并将该电压与阈值电压输入水平进行比较,从而检测过电流。此器件可在 0V 至 36V 的共模电压范围内测量该差分电压信号,与电源电压无关。INA300 器件具有可调阈值范围,此范围由单个外部限值设定电阻器来设置。可选迟滞功能可调节比较器的运行情况,以适应 0mV 至 250mV 的宽输入信号范围。

器件上的开漏警报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(清零锁存时清除报警输出)。器件响应时间设置是可选的,10µs 内即可迅速发出过流警报。

INA300 器件由 2.7V-5.5V 单电源供电运行,最大电源电流消耗为 135µA。INA300 器件的额定工作温度范围为 -40°C 至 +125°C,采用 WSON-10 和 VSSOP-10 封装
