Part Number: TPS23751
I design the PoE PD circuit using a TPS23751.
The specification of our product is satisfied IEEE802.3at(Type2)
At this time, Should I set T2P pin to pass a IEEE802.3.at compliance test?
If so, Could you please tell me how to set about the T2P pin?
I checked the reference circuit(PMP11254), but I couldn't understand it.
so,I set T2P pin a open now.
Thank you for your question. The PoE team is currently out of the office celebrating the U.S. holiday of Labor Day. Please expect a response on Tuesday, 9/3.
Thank you for your interest in Texas Instruments PoE devices.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thank you for your question. Yes the T2P pin is required for IEEE802.3at compliance. The pin is used to detect type 2 PSE's. The T2P pin should be connected to a VC with a resistor. The resistor value can be calculated with the information in section "188.8.131.52 T2P Pin Interface" of the TPS23751 datasheet: http://www.ti.com/lit/ds/symlink/tps23751.pdf
If you accept my connect request I can send you further details in reference to PMP11254 privately. Thank you!
