The MAX6861UK225+ monitors one voltage rail. The reset timeout is adjustable via an external capacitor, giving the designer control over the power-good delay to match the downstream processor's startup sequence. The push-pull output eliminates the need for an external pull-up resistor, saving a component and a board trace.
