TPS23861 Quad Port PoE PSE ControllersTexas Instruments TPS23861 Quad Port Power-Over-Ethernet PSE Controller is an easy-to-use, flexible, IEEE802.3at PSE solution. As shipped, it automatically manages four 802.3at ports without the need for any external control. The TPS23861 automatically detects Powered Devices (PDs) that have a valid signature, determines power requirements according to classification, and applies power. Two-event classification is supported for type-2 PDs. The TPS23861 supports DC disconnection, and the external FET architecture allows designers to balance size, efficiency, and solution cost requirements. The unique pin-out enables 2-layer PCB designs via logical grouping and clear upper and lower differentiation of I 2 C and power pins. This device delivers best-in-class thermal performance, Kelvin accuracy, and low-build cost. In addition to automatic operation, the Texas Instruments TPS23861 supports semi auto-mode via I 2 C control for precision monitoring and intelligent power management. Compliance with the 400ms TPON specification is ensured whether in semi-automatic or automatic mode.
