HI TI experts:
I have encountered a problem when using the Pres pin function of BQ40Z80, and I need your help.
When I did not use the Pres pin as a key switch, it was no problem to hit ESD after connecting 10K to ground.But after I use the Pres pin as a key switch, the ESD that touches 4K and air 8K cannot pass.It seems that this Pres pin is very sensitive, causing the ESD test to fail. Do you have any good suggestions? Looking forward for your reply, thank you.
