For your information, VCC pins short is one of the symptoms of EOS.
In order to avoid electrical damage, the device should always be handled in a static-free environment and all the input signals should remain within specified limits, as recommended in the PSG Data Book and associated application notes, at all times.
Tks for your feedback, but could you pls help to provide more evidence or documents for "VCC pins short is one of the symptoms of EOS"? Or you can release a FA for the case and we can get a official report?
We need to feedback the issue to customer side since the issue appeared in customer production line, just some potential reasons maybe very difficult to persuade the customer side and let the case closed.
