Silicon Labs Quad port PoE/PoE+ PSE Controller Si3452/53

The Si3452 is an IEEE 802.3at™ (D4.2) compliant, quad-port power over Ethernet (PoE) controller for power sourcing equipment (PSE). The Si3452 PoE PSE solution is intended for use in endpoint (switch) or midspans designed to deliver power to PoE PDs, such as multi-radio wireless access points, VoIP phones, pan-tilt-zoom (PTZ) video surveillance cameras, Point-of-sale terminals, and industrial automation equipment. The PoE PSE solution is the industry’s most energy-efficient, quad-port PoE PSE controller. This device supports PoE PSE systems complying with IEEE’s existing 15 W per port PoE standard, as well as the recently-ratified, 30 W per port “PoE+” standard. For proprietary applications, higher power levels to 40 W per port are supported.
