Si3471 PoE Power Sourcing Equipment ICSkyworks Si3471 Power over Ethernet (PoE) Power Sourcing Equipment (PSE) IC is designed for PoE midspans and injectors that do not require a host or microcontroller. The Si3471 integrates one Ethernet port with the IEEE-required Powered Device (PD) detection and classification functionality, and can deliver up to 90W. In addition, it features PD disconnect using DC sense algorithms and a robust multipoint detection algorithm. Intelligent protection circuitry includes input under-voltage detection, output current limit, and short-circuit protection. The Si3471 works autonomously and does not require a host or MCU to program it. The Si3471 is programmed for maximum available power by pulling its configuration pins high or low.
