Dear Experts
My customer followed our EVM for the DVCC and RESET circuit design as follows:
They found RESET drop to below 2V which makes MSP430 hangs up when battery drop to 9V but DVCC still keep 3.3V.
5 pcs shows this situation over totally 2000pcs products.
And this issue happens sometimes (not always) in those 5pcs failed products.
Do you have any comment about this issue?
Should I do any further test or just send those failed for FA analysis?
Thanks for your comment.
