DESCRIPTION  
The DS1831C multisupply monitor and reset monitors up to four system voltages: 2.5V supply, 3.3V (or  
3V) supply, and two additional user configurable voltage monitors. DS1831 power for internal operation  
comes from the higher voltage level of the 3.3V input or the 2.5V input. One of these inputs must be  
greater than 1V for device operation. Pushbutton (manual reset) functionality is provided for the 2.5V
