DESCRIPTION  
The DS1831 Multi-Supply Monitor & Reset monitors up to 4 system voltages: 5 volt supply, 3.3 (or 3)  
volt supply, and 2 additional user configurable voltage monitors. DS1831 power for internal operation  
comes from the higher voltage level of the 3.3 volt input or the 5 volt input. One of these inputs must be  
greater than 1 volt for device operation. Pushbutton (manual reset) functionality is provided for the 5 volt  
reset, the 3.3 volt reset or for all reset outputs by the master pushbutton. The DS1831A replaces one  
reference comparator and the master pushbutton with watchdog and the DS1831B replaces the 3.3V  
PBRST with a last reset status output.
