Maxim Integrated DS1831C

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. The DS1831D replaces one reference comparator and the master pushbutton with watchdog and the DS1831E replaces the 3.3V PBRST with a last reset status output.
