of detecting out-of-tolerance power supply conditions
and warning a processor-based system of impending
power failure.
tolerance, the RESET signal is asserted. On power-up,
RESET is kept active for approximately 200 ms after
the power supply has reached the selected tolerance.
This allows the power supply and microprocessor to
stabilize before RESET is released.
