- TPS23861 — 4-Kanal-Power-over-Ethernet (PoE)-PSE mit 2 Paaren, Typ 2, mit autonomem Modus
The TPS23861 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 I2C and power pins. This delivers best-in-class thermal performance, Kelvin accuracy and low-build cost.
In addition to automatic operation, the TPS23861 supports Semi-Auto Mode via I2C control for precision monitoring and intelligent power management. Compliance with the 400-ms TPON specification is ensured whether in semi-automatic or automatic mode.
