5-Pin Microprocessor Supervisory Circuits With
Watchdog Timer and Manual Reset
________________General Description
The MAX823/MAX824/MAX825 microprocessor (μP)
supervisory circuits combine reset output, watchdog,
and manual reset input functions in 5-pin SOT23 and
SC70 packages. They significantly improve system relia-
bility and accuracy compared to separate ICs or discrete
components. The MAX823/MAX824/MAX825 are specifi-
cally designed to ignore fast transients on V CC .
Seven preprogrammed reset threshold voltages are
available (see Reset Threshold Table ). All three devices
have an active-low reset output, which is guaranteed to
be in the correct state for V CC down to 1V. The MAX823
also offers a watchdog input and manual reset input.
The MAX824 offers a watchdog input and a comple-
mentary active-high reset. The MAX825 offers a manual
reset input and a complementary active-high reset. The
Selector Guide explains the functions offered in this
series of parts.
