DESCRIPTION  
The CAT811 and CAT812 are µP supervisory circuits  
that monitor power supplies in digital systems. The  
CAT811 and CAT812 are direct replacements for the  
MAX811andMAX812inapplicationsoperatingoverthe  
industrial temperature range; both have a manual reset  
input.  
offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V  
systems.  
The CAT811 features a RESET push-pull output (active  
LOW) and the CAT812 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 Vcc  
levels as low as 1.0 V.  
Thesedevicesgeneratearesetsignal,whichisasserted  
whilethepowersupplyvoltageisbelowapresetthreshold  
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  
The CAT811/812 are fully specified over the industrial  
temperature range (-40˚C to 85˚C) and are available in  
a compact 4-pin SOT143 package.
