Power over Ethernet (PoE) solutions
PSEs and PDs for PoE design interoperability and flexibility
Our power over Ethernet (PoE) ICs offer high interoperability, reliability, convenience, and complete system solutions to those wanting to easily deliver power through Ethernet cables. The IEEE Committee has ratified a new PoE standard (IEEE 802.3bt). We have been involved in the standard’s development since inception, and have a full IEEE802.3bt-ready end-to-end portfolio of interoperable powered devices (PD) and power sourcing equipment (PSE) controllers, which will enable power up to 90W at the source (PSE) and 71.3W at the input to loads (PD), making it ideal for end equipment requiring more power than previous standards could support. Examples of new applications include professional audio, digital signage, 5G small cell radio units, industrial access control, and connected lighting.

Use this as the baseboard for the PSE Controller ecosystem. The octal channel, TPS2388x devices are IEEE 802.3bt ready PoE PSE controllers and can be evaluated by using the BOOST-PSEMTHR-007, TPS23881EVM daughter card, and/or TPS23880EVM daughter card working together.
The TPS23881EVM daughter card features the octal channel, TPS23881, IEEE 802.3bt ready PoE PSE controller. When paired with the IEEE 802.3bt ready PSE motherboard BOOST-PSEMTHR-007 (sold separately), user's can evaluate the TPS23881 device.
This Power over Ethernet (PoE) reference design supplies power and data over a single Ethernet cable to a connected LED lighting ballast. This reference provides power to the LED light remotely controlling the brightness and dimming parameters of the LED light while connected to the network.
In 2018 the EA began granting licenses to PoE designs which pass a test suite to demonstrate compliance to the new standard. TI has multiple EA designs and was the first IC supplier to receive a logo.

What is power over Ethernet (PoE)?
PoE is a mature and growing technology used to conveniently deliver power through Ethernet cables to a load rather than adding additional power cords. We offer solutions for both ends of the cable.
