_______________General Desc ription
The MAX823/MAX824/MAX825* microprocessor (μP)
supervisory circuits combine reset output, watchdog,
and manual-reset input functions in a 5-pin SOT23-5
package. They significantly improve system reliability
and accuracy compared to separate ICs or discrete
components. The MAX823/MAX824/MAX825 are
specifically designed to ignore fast transients on V
CC
.
Five preprogrammed reset threshold voltages are
available, designated by the following package
suffixes: L = 4.63V, M = 4.38V, T = 3.08V, S = 2.93V,
and R = 2.63V. 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 MAX824/MAX825 also
have an active-high reset output. The following Selector
Guide explains the functions offered in this series of
parts.
