4-Pin Microprocessor Power Supply Supervisors with Manual Reset
DESCRIPTION
The CAT811 and CAT812 are microprocessor
supervisory 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 140 ms 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 +5.0 V, +3.3 V, +3.0 V and +2.5 V
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 V
cc
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 SOT143 package.
