Hello,
customer ask what the WDT timing is for standard and extended device is when the CCWD cap is not connected. It is different when connected (Table 8-2) but should be same if not connected (Table 8-1). Please check.

    Hello Holger,

    The WDT timing when the CWD cap is not connected is 1600ms (TYP) as in Table 8-1. The WDT timing is the same for both standard and extended devices when the CWD cap is not connected. 

    If a CWD cap is used, the standard and extended device timings will be different according to these two equations. 

    Best,

    Walter
