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 V

supply voltage declines below a preset threshold or

whenever manual reset is asserted. Reset remains

asserted for at least 140ms after V

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

output, while the MAX6712 has an active-high reset out-

put. The reset comparator is designed to ignore fast

transients on V

be in the correct logic state for V

Low supply current makes the MAX6711/MAX6712/

MAX6713 ideal for use in portable equipment. These

devices are available in a 4-pin SC70 package.
