Description：

The device is a current-sensing comparator that detectsovercurrent by measuring the voltage developed across ashunt resistor and comparing the voltage to the thresholdvoltage. The device measures this differential voltagesignal on common-mode voltages which can vary from 0 Vup to 36 V, independent of the supply voltage. The devicefeatures an adjustable threshold range that can be set by asingle external resistor or an external voltage source at thelimit terminal.An open-drain alert output on the device can be configuredto operate in either direct mode where the output statusfollows the input state, or in a latched mode where the alertoutput is cleared when the latch is cleared. The responsetime setting of the device is selectable, which enablesovercurrent alerts to be issued in 10 µs, 50 µs, and 100µs.The device operates from a single 2.7-V to 5.5-V supply,drawing a supply current of 270 µA. The device isspecified over the extended operating temperature rangefrom −40°C to +125°C and is available in the DFN2×2-10and MSOP10 packages.
