The MAX803/MAX809/MAX810 are microprocessor (µP)

supervisory circuits used to monitor the power supplies

in µP and digital systems. They provide excellent circuit

reliability and low cost by eliminating external compo-

nents and adjustments when used with +5V, +3.3V,

+3.0V, or +2.5V powered circuits.

These circuits perform a single function: they assert a

reset signal whenever the V

below a preset threshold, keeping it asserted for at

least 140ms after V

old. Reset thresholds suitable for operation with a vari-

ety of supply voltages are available.

The MAX803 has an open-drain output stage, while the

MAX809/MAX810 have push-pull outputs. The

MAX803’s open-drain RESET output requires a pull-up

resistor that can be connected to a voltage higher than

output, while the MAX810 has an active-high RESET

output. The reset comparator is designed to ignore fast

transients on V

be in the correct logic state for V

Low supply current makes the MAX803/MAX809/

MAX810 ideal for use in portable equipment. The

MAX803 is available in a 3-pin SC70 package, and the

MAX809/MAX810 are available in 3-pin SC70 or SOT23

packages.
