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.

Featured reference design
If you’re wanting to power a LED lighting ballast, use this design and the TPS2372 PD to efficiently send power and data over your Ethernet cable.
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.
