DESCRIPTIOn
The CAT803, CAT809, and CAT80 are supervisory
circuits that monitor power supplies in digital systems. The
CAT803, CAT809, and CAT80 are direct replacements
for the MAX803, MAX809 and MAX80 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 40 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 +5.0V, +3.3V, +3.0V and +2.5V
systems.
The CAT803 has an open-drain RESET output (active
LOW). The CAT803 requires a pull-up resistor on the
reset output.
The CAT809 features a push-pull RESET output (active
LOW) and the CAT80 features a push-pull RESET
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 .0V.
The CAT803, CAT809, and CAT80 are available in both
the compact 3-pin SOT-23 and SC-70 packages.
for Ordering Information details, see page 11 & 12.
Precision monitoring of
+5.0V (-5%, -10%, -20%),
+3.3V (-5%, -10%),
+3.0V (-10%) and
+2.5V (-5%) power supplies
Offered in three output configurations:
- CAT803: Open-Drain Active LOW reset
- CAT809: Push-Pull Active LOW reset
- CAT810: Push-Pull Active HIGH reset
Direct replacements for the MAX803, MAX809
and MAX810 in applications operating over the
industrial temperature range
