DS1233M
OPERATION - POWER MONITOR
The DS1233M provides the functions 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, as
CC
defined by the tolerance of the part selected, the RST signal is asserted. On power-up, RST is kept active
for approximately 350 ms after the power supply has reached the selected tolerance. This allows the
power supply and microprocessor to stabilize before RST is released.
