DESCRIPTION
The CAT811 and CAT812 are microprocessor supervi-
sory circuits that monitor power supplies. The CAT811
and CAT812 are direct replacements for the MAX811
and MAX812 in applications operating over the industrial
temperature range; both have a manual reset input.
These devices generate a reset signal, which is
asserted while the power supply voltage is below a
preset threshold level and for at least 140ms after the
power supply level has risen above that level. The
underlying floating gate technology, AE
2(TM)
used by
Catalyst Semiconductor, makes it possible to offer any
custom reset threshold value. Seven industry
standard threshold levels are offered to support
+5.0V, +3.3V, +3.0V and +2.5V systems.
The CAT811 features a RESET push-pull output
(active LOW) and the CAT812 features a RESET
push-pull output (active HIGH).
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.
The CAT811/812 are fully specified over the industrial
temperature range (-40°C to 85°C) and are available
in a compact 4-pin SOT-143 package.
