PD69108ILQ-TR

Power Over Ethernet (PoE) controllers are a specialized class of power management integrated circuits (PMICs) designed specifically to power devices using a single Ethernet cable. The PD69108ILQ-TR is an advanced PoE controller that provides a complete interface between the power sourcing equipment (PSE) and the powered device (PD), allowing for the transfer of data and power over a single Ethernet connection. It supports both IEEE802.3af and IEEE802.3at PoE/PoE+ standards, allowing it to be used with a wide range of PDs.This article will look at the application fields and working principles of the PD69108ILQ-TR. We will discuss how it is designed to control power to a wide range of PDs, as well as how it can identify and prioritize these devices to ensure that they receive an appropriate amount of power. We will also look at how the controller works to detect and protect against faults, as well as how it is capable of delivering a current up to 30 A for greater power requirements.

Application Fields

The PD69108ILQ-TR is designed to control power and data flow to a wide range of PDs that require power over Ethernet, such as IP phones, access points, cameras, infotainment systems, printers, monitors and many more. It supports both 802.3af and 802.3at PoE and PoE+ standards, meaning it can be used with both existing and emerging PDs. This controller is ideal for applications that require reliable power delivery to devices over Ethernet, such as in commercial and industrial buildings.

Working Principle

The PD69108ILQ-TR is designed to detect limited or excessive power on PoE ports, protecting against over- or under-handed PDs. It provides data transmission priority over power to ensure that PDs can operate reliably and efficiently. It features a four-port SSC/DEC extractor and a 2-port or 4-port arbitrary port extractor, allowing data and power to be transferred over Ethernet.In addition, the controller\'s power classification algorithm is able to detect and quantify the power requirements of connected PDs. This will help to identify which PDs require the most power, and prioritize their power delivery accordingly. It is also capable of delivering up to 30 A for greater power requirements.The controller is equipped with an automatic bridging protection circuit that detects any loss of power supply and limits the current flow to prevent any faults or damage to connected PDs. This provides a better and safer connection for PDs.

Conclusion

The PD69108ILQ-TR is an advanced PoE controller that provides a complete interface between the power sourcing equipment (PSE) and the powered device (PD). It supports both IEEE802.3af and IEEE802.3at PoE/PoE+ standards, making it applicable to a wide range of PDs. Its features include its ability to detect limited or excessive power on PoE ports, providing device data transmission priority over power. It can also classify the power requirements of connected devices and deliver up to 30 A for greater power requirements. Finally, it provides an automatic bridging protection circuit to detect any loss of power and protect connected devices from damage.
