1 / 8 page General Description The MAX6711/MAX6712/MAX6713 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excel- lent circuit reliability and low cost by eliminating exter- nal components and adjustments when used with +5.0V, +3.3V, +3.0V, or +2.5V-powered circuits. They also provide a debounced manual reset input. These circuits assert a reset signal whenever the VCC supply voltage declines below a preset threshold or whenever manual reset is asserted. Reset remains asserted for at least 140ms after VCC has risen above the reset threshold or when manual reset is deasserted. Reset thresholds suitable for operation with a variety of supply voltages are available. The MAX6713 has an open-drain output stage, while the MAX6711/MAX6712 have push-pull outputs. The MAX6713’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The MAX6711/MAX6713 have an active-low reset output, while the MAX6712 has an active-high reset out- put. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the MAX6711/MAX6712/ MAX6713 ideal for use in portable equipment. These devices are available in a 4-pin SC70 package.
