Hi Expert,
My customer have an issue about communication error after doing ESD test.
This behavior is kept until Power OFF/ON. It seem the latch.
Customer guess the ESD was coming from 9pin.
Q1, Could you please let me know the reason of this behavior?
Q2, Can you provide an equivalent circuit diagram for 9-pin and 16-pin input circuits?
Q3, Please tell me recommended terminate method for 9pin/16pin.
Current condition
/EN pulldown with 1kohm. If they change pulldown resister to 0ohm, it was improved.
Thanks
Muk
