Hi, All Gurus,
I finally selected ADM6316xxxX, which has a watchdog time from 100ms, from 71ms~153ms.
It is acceptable.
The outside reset signal will be connected to WDI as following.
I still doubt if it can work as my supposed:
1. Normally WDI=+3.3V,
2. when want reset, WDI=0V,
2.1 if WDI=0V last more than watchdog time, then output low (reset signal).
2.2 if WDI=0V less than watchdog time, then output high, no reset happens.
Right?
Best,
tony liu

Hi,
What I am worried is that outside reset low level can produce two reset signals,
from the down and up transition of outside signal respectively.
Right?
