we would like to detect PSE(POE switch) provide AT or AF to our device.
I guess T2P is suitable signal.
One question,
if PSE provide AF to my device, does T2P keep in high level always or just output a pulse only ?

Hi Pao,
If a type 1 PSE is connected to the TPS23754, the T2P pin will remain high indicating to the load that it is connected to a PSE that can deliver up to 15W to the PD (13W at the end of the cable at the PD).
