MAX16124 Overview
The MAX16122 MAX16125 pushbutton controllers with single-supply monitors monitor one or two pushbuttons and generate a hard reset signal if the buttons are pushed and held for a setup delay. These devices make it easy to “hide” the hard reset function in an existing pushbutton, such as a soft power switch. The devices operate from 1.6V to 5.5V and consume a quiescent current of only 5µA at 3V.
