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
push-pull
output (active low) for the two pinout options.
The CAT853 and CAT863 feature an open drain
RESET
output (active low). Both require a pull-up
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
VCC levels as low as 1.0 V.
