What are Power Over Ethernet ICs

Power Over Ethernet ICs enable the transmission of electrical power alongside data over standard Ethernet cabling by integrating detection, classification, and power control functions. These devices are designed to manage the interface between powered devices and the Ethernet infrastructure while maintaining compliance with defined power delivery mechanisms.

Power Over Ethernet ICs coordinate input power handling, internal regulation, and communication signaling to ensure reliable operation under varying load and network conditions. Their internal architecture supports controlled power negotiation and delivery while preserving data integrity across the Ethernet link.

Key Specifications

• Number of Ports: Defines how many Ethernet-powered interfaces are supported by the IC. This parameter influences system scalability, power distribution complexity, and the level of integration required for multi-port designs.
• Input Voltage: Specifies the voltage range supplied to the IC from the Ethernet power source. This affects internal power conversion design and determines compatibility with upstream power-sourcing equipment.
• Output Voltage: Describes the regulated voltage provided by the IC to downstream circuitry. This parameter is critical for matching the power requirements of the powered device and ensuring stable system operation.
• Output Current: Indicates the amount of load current the IC can deliver while maintaining regulation and protection functions. This directly impacts supported device power levels and thermal performance.
• Communication Standards: Identifies the Ethernet and power delivery standards supported by the IC. This determines interoperability with network equipment and governs how power negotiation and control signaling are implemented.
