INA300
Description
Designed for overcurrent protection applications, the INA300 is a current-sensing comparator that detects overcurrent by measuring the voltage developed across a shunt resistor, and comparing that voltage to the threshold voltage input level. 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.
