My customer is considering TPS23730 and has a question. I would be grateful if you could advise. If the connected PSE only supports up to IEEE.802.3at or af, how would it be classified? In our case, ...

An IEEE standard for High Power over Ethernet (PoE). The 802.3at specification provides 25.5 watts of power compared to the 15.4 watts of 802.3af. See PoE. THIS DEFINITION IS FOR PERSONAL USE ONLY.

An IEEE standard for powering network devices via Ethernet cable. Also known as "Power-over-Ethernet" (PoE), the 802.3af specification provides 48 volts over 4-wire or 8-wire twisted pair.

The most common standards are IEEE 802.3af (PoE), IEEE 802.3at (PoE+), and IEEE 802.3bt (PoE++). PoE classes indicate the power output levels of PoE devices. There are five classes for PoE and ...

IEEE802.3bt / 802.3at / 802.3af POE and Passive POE, as well as a maximum rated power of 600W with POE rated power not less than 500W. Comes with three power options: AC, DC, Battery Modes.

I have found limited discussion about the TI TPS23756 and 802.3at ("PoE+") compliance. Apparently, the negotiation for 802.3at involves two (here simplified) steps: 1. A primary voltage/current ...
