DS1831S+

The DS1831S+ is a multisupply Micromonitor chip in 16 pin NSOIC package. The DS1831 multisupply monitor and reset monitors up to four voltages such as 5V supply, 3.3V supply (or 3V) and two additional user configurable voltages respectively. The DS1831 provides the functions of detecting out of tolerance conditions on a 3.3V (or 3V) and 5V power supply and warning a processor-based system of impending power failure. DS1831 power for internal operation comes from the higher voltage level of the 3.3V input or the 5V input. One of these inputs must be greater than 1V for device operation.
