Power-over-Ethernet (PoE) Solutions for both ends of the cable!

PoE solutions for powered devices and power sourcing equipment

TI offers a complete portfolio of PoE ICs for powered devices (PDs) and power sourcing equipment (PSE). All of TI’s PoE devices are IEEE 802.3af compliant and can be used in a variety of PoE applications such as VoIP telephones, security cameras, RFID readers and wireless access points. TI is also leading the way toward higher-power PoE solutions, with products like the upcoming 802.3at-compliant TPS23754! That's High Performance Analog >> Your Way™.
