DESCRIPTIOꢀ  
■ Precision monitoring of  
+5.0V (-5%, -10%, -20%),  
+3.3V (-5%, -10%),  
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.  
+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  
Thesedevicesgeneratearesetsignal,whichisasserted  
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, AE2(TM) used by Catalyst  
Semiconductor, makes it possible to offer any custom  
resetthresholdvalue.Sevenindustrystandardthreshold  
levels are offered to support +5.0V, +3.3V, +3.0V and  
+2.5V systems.  
■ 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  
■ Available in RoHS-compliant SOT-23 and SC70  
The CAT809 features a push-pull RESET output (active  
LOW) and the CAT810 features a push-pull RESET  
output (active HIGH).  
packages  
APPLICATIOꢀS  
■ Computers  
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.  
■ Servers  
■ Laptops
