CAT811, CAT812  
4-Pin Microprocessor Power Supply Supervisors with Manual Reset  
FEATURES  
DESCRIPTION  
ꢀ Precision monitoring of  
+5.0 V (± 5%, ± 10%, ± 20%),  
+3.3 V (± 5%, ± 10%),  
The CAT811 and CAT812 are microprocessor  
supervisory circuits that monitor power supplies. The  
CAT811 and CAT812 are direct replacements for the  
MAX811andMAX812inapplicationsoperatingoverthe  
industrial temperature range; both have a manual reset  
input.  
+3.0 V (± 10%) and  
+2.5 V (± 5%) power supplies  
ꢀ Manual reset input  
Thesedevicesgeneratearesetsignal,whichisasserted  
whilethepowersupplyvoltageisbelowapresetthreshold  
level and for at least 140 ms after the power supply level  
ꢀ Offered in two output configurations:  
- CAT811: Active LOW reset  
- CAT812: Active HIGH reset  
has risen above that level. The underlying floating gate  
ꢀ Direct replacements for the MAX811 and  
MAX812 in applications operating over the  
industrial temperature range  
2(TM)  
technology, AE  
used by Catalyst Semiconductor,  
makes it possible to offer any custom reset threshold  
value. Seven industry standard threshold levels are  
offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V  
systems.  
ꢀ Reset valid down to V = 1.0 V  
CC  
ꢀ 6 µA power supply current  
ꢀ Power supply transient immunity  
The CAT811 features a RESET push-pull output (active  
LOW) and the CAT812 features a RESET push-pull  
output (active HIGH).  
ꢀ Available in SOT-143 packages with Sn or  
NiPdAu Green Lead finishes.  
ꢀ Industrial temperature range: -40°C to +85°C  
Fast transients on the power supply are ignored and the  
output is guaranteed to be in the correct state at V  
levels as low as 1.0 V.  
cc  
APPLICATIONS  
ꢀ Computers  
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.
