MAX705–MAX708/MAX813L
Low-Cost, μP Supervisory Circuits
General Description
The MAX705–MAX708/MAX813L microprocessor (µP)
supervisory circuits reduce the complexity and number of
components required to monitor power-supply and battery
functions in µP systems. These devices significantly improve
system reliability and accuracy compared to separate ICs or
discrete components.
The MAX705/MAX706/MAX813L provide four functions:
1) A reset output during power-up, power-down, and
brownout conditions.
2) An independent watchdog output that goes low if
the watchdog input has not been toggled within 1.6
seconds.
3) A 1.25V threshold detector for power-fail warning, low-
battery detection, or for monitoring a power supply
other than +5V.
4) An active-low manual-reset input.
The MAX707/MAX708 are the same as the MAX705/
MAX706, except an active-high reset is substituted for
the watchdog timer. The MAX813L is the same as the
MAX705, except RESET is provided instead of RESET.
Two supply-voltage monitor levels are available: The
MAX705/MAX707/MAX813L generate a reset pulse when
the supply voltage drops below 4.65V, while the MAX706/
MAX708 generate a reset pulse below 4.40V. All four parts
are available in 8-pin DIP, SO, and µMAX® packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
