MAX6709/MAX6714 19-2379 Rev 1 12/05 Low-Voltage, High-Accuracy, Quad Voltage Monitors in MAX Package General Description Features The MAX6709/MAX6714 quad voltage monitors provide Monitor Four Power-Supply Voltages accurate monitoring of up to four supplies without any Precision Factory-Set Threshold Options for 5.0V, external components. A variety of factory-trimmed thresh- 3.3V, 3.0V, 2.5V, and 1.8V (Nominal) Supplies old voltages and supply tolerances are available to opti- mize the MAX6709/MAX6714 for specific applications. Adjustable Voltage Threshold Monitors Down to The selection includes input options for monitoring 5.0V, 0.62V 3.3V, 3.0V, 2.5V, and 1.8V voltages. Additional high-input- High-Accuracy (2.0%) Adjustable Threshold impedance comparator options can be used as adjustable voltage monitors, general-purpose compara- Inputs tors, or digital-level translators. Low Supply Current The MAX6709 provides four independent open-drain MAX6709: 35A outputs with 10A internal pullup to V . The MAX6714 CC MAX6714: 60A provides an active-low, open-drain RESET output with Four Independent, Active-Low, Open-Drain integrated reset timing and three power-fail comparator outputs. Outputs with 10A Internal Pullup to V CC Each of the monitored voltages is available with trip 140ms (min) Reset Timeout Period thresholds to support power-supply tolerances of either (MAX6714 only) 5% or 10% below the nominal voltage. An internal 2.0V to 5.5V Supply Voltage Range bandgap reference ensures accurate trip thresholds across the operating temperature range. Immune to Supply Transients The MAX6709 consumes only 35A (typ) of supply cur- Fully Specified from -40C to +85C rent. The MAX6714 consumes only 60A (typ) of supply Small 10-Pin MAX Package current. The MAX6709/MAX6714 operate with supply voltages of 2.0V to 5.5V.
