Part Number: TPS23730
Other Parts Discussed in Thread: TPS23880

My customer is testing a PD board they designed using the TPS23730.

The PSE board will use commercial products.

Is there a difference in connection between the 802.3bt board and the POE++ board?

Are there any differences in specifications between 802.3bt and PoE++?

Thank you.

PoE++ is not exactly the same with 802.3bt.

You can find the TI training video title "TPS23880 working with noncompliant high power PDs (UPoE, PoE++ and PoH)" for more information https://www.ti.com/video/series/power-over-ethernet-poe-training-series.html

PoE++ PSE power can be slightly higher than BT PSE at Class-6 (65 W and 60 W). As well as TPS23730 hotswap's current is below 1.2 A, it should be no issue to use TPS23730 with a PoE++ PSE.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
