OPERATION — POWER MONITOR
The DS1816 provides the function of detecting out-of-tolerance power supply conditions and warning a
processor-based system of impending power failure. When V
signal is asserted. On power-up,
reached the selected tolerance. This allows the power supply and microprocessor to stabilize before
is released.
