What is a Power over Ethernet or PoE IC?
Power over Ethernet or PoE is a technology that is used for delivering DC power to devices over copper ethernet cables. Power over Ethernet Technology consists of two important parts – power sourcing equipment (PSE) and power device (PD). The power sourcing equipment is a device that provides power on the ethernet cable, and the device that receives the power from the ethernet cable is called the powered device. The PSE equipment consists of PoE ICs that support power & data transmission over the ethernet cable. PoE can be used to power devices up to 100 W.
In 1999, both the IEEE and the Ethernet Alliance started working to standardize PoE to ensure interoperability across a broader range of connected powered devices and power sourcing equipment.
Key features of PoE ICs:
- Designed to use in both end-span and mid-span.
- Undervoltage detection.
- Output current limit function.
- Short circuit protection.
- Over-temperature protection.
