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.
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.

WDI
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.
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.
