Si3474 Data Sheet Up to four 802.3bt or eight 802.3at Ethernet Port PoE PSE Controllers The Si3474 is a fully programmable, 50 to 57 V power management controller for IEEE 802.3af, 802.3at, and 802.3bt pliant Power Sourcing Equipment (PSE). Designed for use in PSE endpoints (switches), the Si3474 integrates eight independent ports, each with the IEEE-required powered device (PD) detection and classification functionality. When used in 802.3af/802.3at (two-pair power) mode each PSE port supports one Ethernet connection, for a total of eight PoE Ethernet connections. 802.3bt operation (four-pair power) uses two PSE ports per Ethernet connection, for a total of four PoE Ethernet...
