Texas Instruments INA300/INA300-Q1 Current-Sense Comparator
Texas Instruments INA300/INA300-Q1 High- or Low-Side Current-Sense Comparator is a high common-mode, current-sensing comparator that is configured to detect overcurrent conditions through measuring the voltage developed across a current sensing or shunt resistor. The device can measure this differential voltage signal on common-mode voltages that can vary from 0V up to 36V, independent of the supply voltage. The device features an adjustable threshold range that is set using a single external limit-setting resistor. A selectable hysteresis feature enables adjustable operation of the comparator to accommodate the wide input signal range of 0mV to 250mV. The INA300-Q1 devices are AEC-Q100 qualified for automotive applications.
