Other Parts Discussed in Thread: TPS23861
Hi TI expert：
i use the TPS2373+ TPS23861 in my PoE project，
When there is no DC JACK input, add the surge ±4KV on RJ 45 12/36 Port， the testing is pass.
but when use the DC JACK, and the only add the surge ±0.5KV on RJ45 12/36 Port，the testing is fail， and the TPS2373 damage.
Can you give me some advice to avoid it, thank.
