CAT803, CAT809, CAT810
3-Pin Microprocessor Power Supply
Supervisors
Features
DEscription
■ Precision monitoring of
+5.0V (-5%, -10%, -20%),
+3.3V (-5%, -10%),
+3.0V (-10%) and
+2.5V (-5%) power supplies
The CAT803, CAT809, and CAT810 are supervisory
circuits that monitor power supplies in digital systems.The
CAT803, CAT809, and CAT810 are direct replacements
for the MAX803, MAX809 and MAX810 in applications
operating over the industrial temperature range.
■ 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
■ Reset valid down to VCC = 1.0V
■ 6µA power supply current
■ Power supply transient immunity
■ Industrial temperature range: -40ºC to +85ºC
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, AE2(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.

Available in
packages
RoHS-compliant
SOT-23
and
SC70 Thewww.DataSheet4U.com CAT809 features a push-pull RESET output (active
LOW) and the CAT810 features a push-pull RESET
Applications
output (active HIGH).
■ Computers
■ Servers
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 1.0V.
■ Laptops
■ Cable modems
The CAT803, CAT809, and CAT810 are available in both
the compact 3-pin SOT-23 and SC70 packages.
■ Wireless communications
■ Embedded control systems
■ White goods
