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