Part Number: TPS23734

Dear Specialists,

My customer is considering TPS23734 and has a question.

I would be grateful if you could advise.

---

We are not familiar with IEC62368-3, so could you please let us know.

Part 3 of IEC62368-3 has a description about power supply from signal line.

What is the relationship with POE?
Which class is required

I appreciate your great help in advance.

Best regards,

Shinichi

Hello Shinichi,

We conform our parts to IEEE802.3.bt.

Quickly glancing at IEC62368, our voltages are ES1 since it is <60V.

ES3 is anything >120V.

If this post answers your question, please indicate so by marking this thread as resolved. Thank you.

Regards,
