1. Over-temperature limits are guaranteed by design, not production tested.

2. Watchdog timeout period C is not available on AAT3513, AAT3514, and AAT3518.

3. WDI is internally serviced within the watchdog period if WDI is left unconnected.

4. 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.
