Hi Sir 

May TPS2373(and TPS23751) have pin output or other way to know what PSE device connected?

Because customer want to turn off some function when then connect much low power PSE.

    Hi Bogey,

    The condition you are describing is called demotion in the PoE standard (when a PSE power level available is lower than what the PD is requesting). I recommend looking at the training below that describes demotion and how the PD uses TPH/TPL/BT (in TPS2373) and T2P (in TPS23751) to show the PD what Type PSE is connected to the PD.

    Regards,
