CAT803, CAT809, CAT810  
3-Pin Microprocessor Power Supply Supervisors  
FꢀATꢁꢂꢀS  
DESCRIPTIOꢀ  
The CAT803, CAT809, and CAT8ꢀ0 are supervisory  
circuitsthatmonitorpowersuppliesindigitalsystems.The  
CAT803, CAT809, and CAT8ꢀ0 are direct replacements  
for the MAX803, MAX809 and MAX8ꢀ0 in applications  
operating over the industrial temperature range.  
■ Precision monitoring of  
+5.0V (-5%, -10%, -20%),  
+3.3V (-5%, -10%),  
+3.0V (-10%) and  
+2.5V (-5%) power supplies  
Thesedevicesgeneratearesetsignal,whichisasserted  
whilethepowersupplyvoltageisbelowapresetthreshold  
level and for at least ꢀ40 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.  
■ 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  
■ ꢂeset valid down to VCC = 1.0V  
■ 6µA power supply current  
The CAT803 has an open-drain RESET output (active  
LOW). The CAT803 requires a pull-up resistor on the  
reset output.  
■ Power supply transient immunity  
■ Industrial temperature range: -40ºC to +85ºC  
The CAT809 features a push-pull RESET output (active  
LOW) and the CAT8ꢀ0 features a push-pull RESET  
output (active HIGH).  
■ Available in RoHS-compliant SOT-23 and SC-70  
packages  
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 ꢀ.0V.  
APPLICATIOꢀS  
■ Computers  
■ Servers
