Texas Instruments PINA381A1IDSGR

The INA381 device includes both a 26-V common-mode, current-sensing amplifier and a high-speed comparator configured to detect overcurrent conditions through measuring the voltage developed across a current-shunt resistor and comparing that voltage to a defined threshold limit set by the comparator reference pin. The current-shunt monitor can measure differential voltage signals on common-mode voltages that can vary from –0.2 V up to 26 V, independent of the supply voltage.

The open-drain alert output can be configured to operate in either a transparent mode where the output status follows the input state or in a latched mode where the alert output is cleared when the latch is reset. The standalone comparator alert response time is under 5 µs, allowing for quick detection of overcurrent events. The total system overcurrent protection provided by the INA381 is under 10 µs.

This device operates from a single 2.7-V to 5.5-V supply, drawing a maximum supply current of 400 µA. The device is specified over the extended operating temperature range (–40°C to +125°C), and is available in an 8-pin WSON package.
