We are using the SC18IM700IPW
We have had issues at -40C and also at +79 C with the parts not functioning.
When they fail they are unresponsive on the bus.
There are 2 applications within our company that have now failed in a similar manner.
We have been using these parts since 2011 and only recently have seen this issue.
If you could please shed any light on this it would be appreciated.
Thanks,
John Eckland
1: do you mind share with us your schematic?
2: do you do a cross test with recently batch sc18im700 with previously perfect board?
