OPERATION - POWER MONITOR

The DS1817 provides the function of detecting out-of-tolerance power supply conditions and warning a

processor based system of impending power failure. When VCC is detected as out-of-tolerance, the RST

signal is asserted. On power-up, RST is kept active for approximately 150 ms after the power supply has

reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RST

is released.
