OPERATION – POWER MONITOR
The DS1233 provides the functions of detecting out–of–
tolerance power supply conditions and warning a pro-
cessor–based system of impending power failure.
When V
CC
is detected as out–of–tolerance, as defined
by the tolerance of the part selected, the RST signal is
asserted. On power–up, RST is kept active for approxi-
mately 350 ms after the power supply has reached the
selected tolerance. This allows the power supply and
microprocessor to stabilize before RST is released.
OPERATION – PUSHBUTTON RESET
The DS1233 provides for a pushbutton switch to be con-
nected to the RST output pin. When the DS1233 is not
in a reset cycle, it continuously monitors the RST signal
for a low going edge. If an edge is detected, the DS1233
will debounce the switch by pulling the RST line low. Af-
ter the internal timer has expired, the DS1233 will con-
tinue to monitor the RST line. If the line is still low, the
DS1233 will continue to monitor the line looking for a ris-
ing edge. Upon detecting a release, the DS1233 will
force the RST line low and hold it low for 350 ms.
NOTE:
For proper operation with an external pushbutton, a ca-
pacitor between 100 pF and 0.01
μ
F must be connected
between RST and ground. In applications where addi-
tional reset current is required, a minimum capacitance
of 500 pF should be used, along with a parallel external
pull–up resistor of 1K
minimum.
