DS1817
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 V
is detected as out-of-tolerance, the RST

CC
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.
