概述

The device is a current-sensing comparator that detects overcurrent by measuring the voltage developed across a shunt resistor and comparing the voltage to the threshold voltage. The device measures this differential voltage signal on common-mode voltages which can vary from 0 V up to 36 V, independent of the supply voltage. The device features an adjustable threshold range that can be set by a single external resistor or an external voltage source at the limit terminal.

An open-drain alert output on the device can be configured to operate in either direct mode where the output status follows the input state, or in a latched mode where the alert output is cleared when the latch is cleared. The response time setting of the device is selectable, which enables overcurrent alerts to be issued in 10 µs, 50 µs, and 100 µs.

The device operates from a single 2.7-V to 5.5-V supply, drawing a supply current of 270 µA. The device is specified over the extended operating temperature range from −40°C to +125°C and is available in the DFN2×2-10 and MSOP10 packages.
