Hi BU team
My customer has below concern on the solution in below link on tusb501-Q1 short-to-battery protection. Would you help share your comments?
(+) TUSB501-Q1: short to battery - Interface forum - Interface - TI E2E support forums
1. Under which condition a 1 or 2 ohm resistor between the ESD diode and the device are needed to protect the 501 from incoming current, ESD or shott-to-battery?
2. what is the suggested package size for this small resistor?

You would also need a 1 or 2 ohm resistor between the ESD diode and the device to protect the 501 from incoming current. Note that this resistance may slightly affect your signal integrity.
In Rx side, why is AC coupling capacitors 330nF instead of 100nF?
If no available higher 16V rated voltage for 0402 cap package, is the cap with 220nF /16V/0402 ok ? Here the maximum battery is 16V.
Thanks
