PIN FUNCTIONS
LTC694-3.3/LTC695-3.3
WDI: Watchdog Input. WDI is a three-level input. Driving
WDI either high or low for longer than the watchdog timeout
period, forces both RESET and WDO low. Floating WDI
disables the watchdog timer. The timer resets itself with
each transition of the watchdog input (see Figure 11).

WDO: Watchdog Logic Output. When the watchdog input
remains either high or low for longer than the watchdog
timeout period, WDO goes low. WDO is set high whenever
there is a transition on the WDI pin, or LOW
low. The watchdog timer can be disabled by floating WDI
(see Figure 11).
