5-Pin Microprocessor Supervisory Circuits With  
Watchdog Timer and Manual Reset  
________________General Description  
Features  
The MAX823/MAX824/MAX825 microprocessor (µP)  
supervisory circuits combine reset output, watchdog,  
and manual reset input functions in 5-pin SOT23 and  
SC70 packages. They significantly improve system relia-  
bility and accuracy compared to separate ICs or discrete  
components. The MAX823/MAX824/MAX825 are specifi-  
♦ Precision Monitoring of +2.5V, +3V, +3.3V, and  
+5V Power Supplies  
♦ Operating Current: 6µA (MAX823L/M) (SC70)  
2µA (MAX825T/S/R/Z/Y) (SC70)  
♦ Fully Specified Over Temperature  
♦ 140ms min Power-On Reset  
cally designed to ignore fast transients on V  
.

Seven preprogrammed reset threshold voltages are  
available (see Reset Threshold Table). All three devices  
have an active-low reset output, which is guaranteed to

be in the correct state for V  
down to 1V. The MAX823  
CC  
(MAX823/MAX824)  
also offers a watchdog input and manual reset input.  
The MAX824 offers a watchdog input and a comple-  
mentary active-high reset. The MAX825 offers a manual  
reset input and a complementary active-high reset. The  
Selector Guide explains the functions offered in this  
series of parts.  
♦ Manual Reset Input (MAX823/MAX825)  
♦ No External Components
