Microprocessor Monitor  
MAX132  
General Description  
Features  
o Consumes 1/10th the Power of the DS1232  
The MAX1232 microprocessor (µP) supervisory circuit  
provides µP housekeeping and power-supply supervi-  
sion functions while consuming only 1/10th the power of  
the DS1232. The MAX1232 enhances circuit reliability  
in µP systems by monitoring the power supply, monitor-  
ing the software execution, and providing a debounced  
manual reset input. The MAX1232 is a plug-in upgrade  
of the Dallas DS1232.  
o Precision Voltage Monitor—Adjustable +4.5V  
or +4.75V  
o Power-OK/Reset Pulse Width—250ms Min  
o No External Components  
o Adjustable Watchdog Timer—150ms, 600ms,  
or 1.2s  
A reset pulse of at least 250ms duration is supplied on  
power-up, power-down, and low-voltage brownout  
conditions (5% or 10% supply tolerances can be  
selected digitally). Also featured is a debounced man-  
ual reset input that forces the reset outputs to their  
active states for a minimum of 250ms. A digitally pro-  
grammable watchdog timer monitors software execu-  
tion and can be programmed for timeout settings of  
150ms, 600ms, or 1.2s. The MAX1232 requires no  
external components.  
o Debounced Manual Reset Input for External  
Override  
o Available in 8-Pin PDIP/SO and 16-Pin Wide SO
