INA300-Q1 Overview
Description
The INA300-Q1 is a high common-mode, currentsensing comparator that detects overcurrent conditions by measuring the voltage developed across a current-sensing or shunt resistor. The device measures this differential voltage signal on commonmode voltages that can vary from 0 V up to 36 V, independent of the supply voltage.
