INA381 Overview
The INA381 includes both a 26-V mon-mode, current-sensing amplifier and a high-speed parator. This device detects overcurrent conditions by measuring the voltage developed across a current-shunt resistor and paring that voltage to a user-defined threshold limit set by the parator reference pin. The current-shunt monitor can measure differential voltage signals on monmode voltages that vary from 0.2 V up to 26 V,...
