Product Details

The Silicon Lab Si3471 is a fully autonomous Power over Ethernet (PoE) Power Sourcing Equipment (PSE) device. It is fully IEEE 802.3bt compliant and compatible with IEEE 802.3af and 802.3at. It is optimized for use in PSE mid-spans and injectors that do not require a host or MCU. The Si3471 integrates one Ethernet port with the IEEE-required powered device (PD) detection and classification functionality. In addition, it features powered device (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.
