CAT809, CAT810  
3-Pin Microprocessor Power Supply Supervisors  
FEATURES  
DESCRIPTION  
Precision monitoring of  
+5.0 V ( 5%, 10%, 20%),  
+3.3 V ( 5%, 10%),  
The CAT809 and CAT810 are µP supervisory circuits  
that monitor power supplies in digital systems. The  
CAT809 and CAT810 are direct replacements for the  
MAX809andMAX810inapplicationsoperatingoverthe  
industrial temperature range.  
+3.0 V ( 10%) and  
+2.5 V ( 5%) power supplies  
Offered in two output configurations:  
- CAT809: Active LOW reset  
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  
offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V  
systems.  
- CAT810: Active HIGH reset  
Direct replacements for the MAX809 and  
MAX810 in applications operating over the  
industrial temperature range  
Reset valid down to V = 1.0 V  
CC  
6 µA power supply current  
Power supply transient immunity  
The CAT809 features a RESET push-pull output (active  
LOW) and the CAT810 features a RESET push-pull  
output (active HIGH).  
Available in SOT-23 and SC70 packages with  
Sn or NiPdAu GREEN lead finish  
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 Vcc  
levels as low as 1.0 V.  
APPLICATIONS  
Computers  
The CAT809/810 are fully specified over the industrial  
temperature range (-40°C to 85°C) and are available in  
compact 3-pin SOT23 and SC70 packages.
