DESCRIPTION
The CAT853, CAT863, CAT859, and CAT869 are
supervisory circuits that monitor power supplies in
digital systems.
These devices generate a reset signal, which is
asserted while the power supply voltage is below a
preset threshold level and for at least 140 ms after the
power supply level has risen above that level. Industry
standard threshold levels are offered to support
+3.3 V or 5.0 V systems.
The CAT859 and CAT869 feature a RESET
output (active low) for the two pinout options.
The CAT853 and CAT863 feature an open drain
¯¯¯¯¯¯ output (active low). Both require a pull-up
RESET
resistor on the RESET output.
Fast transients on the power supply are ignored and
the output is guaranteed to be in the correct state at
