TPS23881 8-Channel Power-Over Ethernet PSE

Texas Instruments TPS23881 8-Channel Power-Over Ethernet PSE is a power-sourcing equipment (PSE) controller engineered to insert power into Ethernet cables per the IEEE 802.3bt standard. The eight individual power channels can be configured in any combination of 2-pair (1-channel) or 4-pair (2-channel) PoE Ports. The PSE controller can detect powered devices (PDs) that have a valid signature, determine the power requirements of the devices according to their classification, and apply power.
