Multi-port PSE Controllers

Our Power Sourcing Equipment (PSE) solutions implement the latest IEEE 802.3bt standard to power multi-Ethernet port switches, gateways, and routers. Si3474 powers up to four 802.3bt 4-pair Ethernet ports with 90 W per port and supports thermally efficient 200mΩ current sense resistors. It is fully backwards compatible with 30 W and 15 W devices. The new Si3472 powers up to four 802.3bt 2-pair Ethernet ports with up to 45 W per port.
