This is the datasheet of DS1231/S power monitor chip. This chip can warn the processor of an impending power failure, provide an orderly shutdown time, and prevent the processor from destroying nonvolatile memory during power transients. It will also automatically restart the processor after power is restored. This chip is suitable for linear or switching power supplies and can adjust to the hold time of the power supply. It also supplies necessary signals for processor interface. This chip can accurately monitor 5% or 10% VCC and can replace power-up reset circuitry. It does not require external capacitors and is available in an optional 16-pin SOIC surface mount package.
