Note 1: Over-temperature limits are guaranteed by design, not production tested.
Note 2: This is the minimum time RESET must be held low by an external pulldown source to set the active pullup flip-flop.
Note 3: Measured from RESET V

to (0.8 x V
CC
), Open Circuit Output.
Note 4: Watchdog timeout period C is not available on AAT3513, AAT3514, and AAT3518.
Note 5: WDI is internally serviced within the watchdog period if WDI is left unconnected.
Note 6: The WDI input current is specified as the average input current when the WDI input is driven high or low. The WDI input is
designed for a three-stated-output device with a 10μA maximum leakage current and capable of driving a maximum capacitive load of
200pF. The three-state device must be able to source and sink at least 200μA when active.
