Power over Ethernet (PoE) Chipsets: Enabling Power and Data Over a Single Cable
Power over Ethernet (PoE) chipsets are integrated circuits that enable both power and data transmission through standard Ethernet cables (like Cat5e or Cat6). This technology eliminates the need for separate power wiring, making network installations simpler, cleaner, and more cost-effective.
PoE chipsets are essential components in devices such as IP cameras, VoIP phones, wireless access points, smart lighting systems, and industrial automation equipment. They are used in both power sourcing equipment (PSE) like PoE switches and powered devices (PD) like IP cameras and sensors.
How PoE Chipsets Work
A PoE chipset typically includes:
Detection & Classification Circuits: Ensure only PoE-compatible devices receive power.
DC-DC Converter: Converts the incoming voltage to required device levels.
