WDS
Watchdog Select Input. WDS selects the watchdog mode. Connect
WDS to ground to select normal mode and the watchdog timeout
period. Connect WDS to V
CC
to select extended mode, multiplying the
basic timeout period by a factor of 128. A change in the state of WDS
clears the watchdog timer.

SET1
Logic Input. SET1 selects the watchdog window ratio or disables the
watchdog timer. See Table 1.

WDI
Watchdog Input.
MAX6746
MAX6751: A falling transition must occur on WDI within the
selected watchdog timeout period or a reset pulse occurs. The
watchdog timer clears when a transition occurs on WDI or whenever
RESET
is asserted. Connect SWT to ground to disable the watchdog
timer function.
MAX6752/MAX6753: WDI falling transitions within periods shorter than
t
WD1
or longer than t
WD2
force
RESET
to assert low for the reset timeout
period. The watchdog timer begins to count after
RESET
is deasserted.
The watchdog timer clears when a valid transition occurs on WDI or
whenever
RESET
is asserted. Connect SET0 high and SET1 low to
disable the watchdog timer function. See the
Watchdog Timer
section.

RESET
Push/Pull or Open-Drain Reset Output.
RESET
asserts whenever V
CC
or
RESET IN drops below the selected reset threshold voltage (V
TH
or
V
RESET IN
, respectively) or manual reset is pulled low.
RESET
remains
low for the reset timeout period after all reset conditions are deasserted,
and then goes high. The watchdog timer triggers a reset pulse (t
RP
)
whenever a watchdog fault occurs.

is the power-supply input and the input for fixed
threshold V
CC
monitor.
