... MAX A 0.5 sense resistor is a good choice in this application. Undervoltage/Overvoltage Detection—MIC2588 The MIC2588 has “UV” and “OV” input pins. These pins can be used to detect input supply rail undervoltage and overvoltage conditions. Undervoltage lockout prevents energizing the load until the supply input is stable and within tolerance similar ...
