A variety of factory-trimmed threshold voltages and supply tolerance are available to optimize the PT7M6709/6714 for specific applications. The selection includes input options for monitoring 5.0V, 3.3V, 3.0V, 2.5V and 1.8V voltages. Additional high- input impedance comparator options can be used as adjustable voltage monitors, general-purpose compare- ators, or digital-level translators. The PT7M6709 provides four independent open-drain outputs with 10μA internal pull-up to Vcc. The PT7M6714 provides an active-low, open-drain RESET output with integrated reset timing and three power-fail comparator outputs. Each of the monitored voltages is available with trip thresholds to support power-supply tolerances of either 5% or 10% below the nominal voltage. An internal bandgap reference ensures accurate trip thresholds across the operating temperature range. The PT7M6709 consumes only 15μA (typical) of supply current. The PT7M6714 consumes only 20μA (typical) of supply current. The PT7M6709/6714 operates with supply voltages of 2.0V to 5.5V. An internal under- voltage lockout circuit forces all four digital outputs low when Vcc drops below the minimum operating voltage. The four digital outputs have weak internal pull-ups to Vcc, accommodating wire-ORed connections. Each input threshold voltage has an independent output. The PT7M6709/6714 are available in MSOP-10 packages and operate over the extended (-40°C to + 85°C) temperature range.
