ZXCT1081 High Side Current Sense Monitor

The ZXCT1081 from Zetex requires a single, low-value sense resistor to accurately measure high side currents. The Sense Monitor eliminates disruption ground plane when sensing a load current. A separate supply pin allows functioning to continue under short circuit conditions, giving an end-stop voltage at output. Operating range of 3V to 40V.
