INA381A1IDSGR, Current Sense Amplifiers 26-V, 350-kHz current sense amplifier with integrated over-current comparator 8-WSON -40 to 125

Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Current Sense AmplifiersINA381/INA381-Q1 Current Sensing Amplifiers Texas Instruments INA381/INA381-Q1 Voltage Output Current Sensing Amplifiers offer both a 26V common-mode, current-sensing amplifier and a high-speed comparator configured to detect overcurrent conditions. This is achieved by 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. This can vary from –0.2V up to 26V, independent of the supply voltage. The open-drain alert output can be configured to operate in either a transparent mode or in a latched mode. The transparent mode produces an output status that follows the input state. The latched mode sends the alert output until it is cleared when the latch is reset. Allowing for quick detection of overcurrent events, the standalone comparator alert response time is under 3µs. The total system overcurrent protection offered by the device is under 10µs. The Texas Instruments INA381/INA381-Q1 draws a maximum supply current of 350µA while operating from a single 2.7V to 5.5V supply. The specified operating temperature range (–40°C to +125°C). The INA381-Q1 devices are AEC-Q100 qualified for automotive applications.
