Si3454 Power Over Ethernet (PoE) and Power Sourcing Equipment (PSE) Controller
The Si3454 PoE PSE Controller is available in a QFN38 package. The device supports both the original 15 W per port PoE standard, as well as the 30 W per port “PoE+” standard. The Si3454 enables the application of PoE power to Ethernet RJ45 jack ports, monitoring power conditions, detecting and dealing with faults, detecting valid Powered Devices (PDs), and cutting off port power when connected PDs are removed. Each port’s supply voltage and current are measured and monitored in real-time and may be accessed via the I²C interface, enabling sophisticated system-level power management and control.
