RESET
+5 V Power Supply Input.
0 V. Ground reference for all signals.
Logic Output.
RESET
goes low whenever V
CC
falls below the reset voltage threshold (4.65 V
typ).
RESET
remains low for a minimum of
140 ms after V
CC
returns to 5 V.
RESET
also
goes low for a minimum of 140 ms if the watchdog
timer is enabled but not serviced within its time-
out period.
Watchdog Input. WDI is a three level input. If
WDI remains either high or low for longer than
the watchdog timeout period,
RESET
pulses low
and
WDO
goes low. T he timer resets with each
transition on the WDI line. T he watchdog timer
may be disabled if WDI is left floating or is driven
to midsupply.
(SOIC packages only) Logic Output. RESET is
an active high output. It is the inverse of
RESET
.
(SOIC ADM8699 only) Logic Output. T he
Watchdog Output,
WDO
, goes low if WDI
remains either high or low for longer than the
watchdog timeout period.
WDO
is set high by the
next transition at WDI. If WDI is unconnected or
at midsupply, the watchdog timer is disabled and
WDO
remains high.
