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 +3.3V or 5.0V 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 V
cc
levels as low as 1.0V.
