MAX6826-MAX6831
Dual Ultra-Low-Voltage SOT23 µP Supervisors
with Manual Reset and Watchdog Timer
General Description
The MAX6826–MAX6831 are ultra-low-voltage micropro-
cessor (µP) supervisory circuits designed to monitor two
power supplies and have manual reset and watchdog
input functions. These devices assert a system reset
if any of the monitored supplies fall below the prepro-
grammed thresholds, and maintain reset for a minimum
timeout period after the supplies rise above the threshold.
Microprocessor supervisors significantly improve system
reliability and accuracy compared to separate ICs or
discrete components. These devices monitor primary
voltages from +1.8V to +5.0V and secondary voltages
from +0.9V to +2.5V. These devices are guaranteed to be
in the correct state for V
CC
down to +1.0V.
A variety of preprogrammed reset threshold voltages
are available (see the
Threshold Suffix Guide).
The
devices include manual reset and watchdog inputs.
The MAX6829/MAX6830/MAX6831 provide a factory-
trimmed threshold to monitor a 2nd voltage down to
+0.9V. The MAX6826/MAX6829 have a push-pull
RESET,
the MAX6827/MAX6830 have a push-pull
RESET and the MAX6828/MAX6831 have an open-drain
RESET.
The MAX6826/MAX6827/MAX6828 have an
auxiliary monitor that allows user adjustable input to
monitor voltages down to +0.6V. see
Selector Guide
for
functions available.
