DESCRIPTION
The CAT809 and CAT810 are
μ
P supervisory circuits
that monitor power supplies in digital systems. The
CAT809 and CAT810 are direct replacements for the
MAX809 and MAX810 in applications operating over the
industrial temperature range.
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 CAT809 features a
RESET
push-pull output (active
LOW) and the CAT810 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 CAT809/810 are fully specified over the industrial
temperature range (-40C to 85C) and are available in
compact 3-pin SOT23 and SC70 packages.
