Power Over Ethernet

The EFP01 Energy Friendly Power Management IC (PMIC) is an extremely flexible, highly efficient, multi-output power management IC, providing complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices. The EFP01 can operate over a wide input voltage range (0.8 to 5.5 V) with quiescent current as low as 150 nA.

Our family of PoE Powered Devices integrate an IEEE compliant PoE interface and a high-efficiency dc-dc converter to simplify design, reduce bill of materials and speed time-to-market for a wide range of industrial and communications applications. The PoE PD EVB portfolio includes non-isolated and isolated converter designs with a wide range of power output options. All EVBs include detailed performance measurements, schematics and PCB layout in the detailed User Guide.

Our family of IEEE-compliant PoE PSE Controllers include single and multi-port devices. Single port PSE devices simplify the design of products such as PoE injectors, conference phones, and single port mid-spans. Multi-port PSE devices add PoE to Ethernet switches, security recording devices, industrial Ethernet switches and other multi-port systems. These devices include an autonomous and hosted operating mode with a rich interface for efficient power management.
