The MAX6709/MAX6714 quad voltage monitors provide accurate monitoring of up to four supplies without any external components. A variety of factory-trimmed threshold voltages and supply tolerances are available to optimize the MAX6709/MAX6714 for specific applications. The selection includes input options for monitoring 5.0V, 3.3V, 3.0V, 2.5V, and 1.8V voltages. Additional high-inputimpedance comparator options can be used as adjustable voltage monitors, general-purpose comparators, or digital-level translators. The MAX6709 provides four independent open-drain outputs with 10A internal pullup to VCC. The MAX6714 provides an active-low, open-drain RESET output with integrated reset timing and three power-fail comparator outputs.
