DESCRIPTION

The DS1831C Multi-Supply Monitor & Reset monitors up to 4 system voltages: 2.5 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 2.5 volt input. One of these inputs must

be greater than 1 volt for device operation. Pushbutton (manual reset) functionality is provided for the

2.5 volt reset, the 3.3 volt reset or for all reset outputs by the master pushbutton. The DS1831D replaces

one reference comparator and the master pushbutton with watchdog and the DS1831E replaces the

3.3-volt PBRST with a last reset status output.

TOL and TD inputs allow user configuration of the DS1831 for multiple applications. The TOL inputs

configure the tolerance for the specified output and the TD inputs configure the reset time delays.
