Power over Ethernet (PoE) technology is a technology that allows powered devices to be remotely powered over Ethernet cabling. It is particularly useful in applications where power outlets are not available, such as remote equipment, or when the powered device needs to be moved around. The PD69008 is a Power over Ethernet (PoE) Controller that is designed to provide the power, control, and signal required to power PoE devices. The PD69008 provides an integrated solution, which eliminates the need for multiple components.

PD69008 Overview

The PD69008 is a Power over Ethernet (PoE) Controller, containing an integrated High Voltage (HV) Power MOSFET and Control IC. The device is designed to provide an integrated PoE platform for both power sourcing and power delivery applications. It supports up to 120W of power delivery when sourcing from a 24V (up to 60W when sourcing from 48V) and provides up to 98W of power delivery when sourcing from 802.3af PoE/ PoE+ compatible source. The device is also able to limit the power load to 50W and detect potential faults in the system.

The PD69008 is equipped with an integrated control IC that offers a wide range of features. The IC includes on-board protection, status monitoring, and fault detection. The on-board protections include over-current, over-voltage, under-voltage, over-temperature, and over-power. These features ensure the safety of the bulk of the system in the event of a failure or fault.

The PD69008 also features an integrated filter to reduce interference from EMI sources, allowing for improved data integrity and higher performance in high-speed applications. It also features integrated optical feedback for enhanced current sensing accuracy, allowing for better accuracy when power delivery is critical. The PD69008 also integrates advanced power management features including power sequencing, which allows for the simultaneous powering of multiple devices while still maintaining power efficiency.

Application Field and Working Principle

The PD69008 is a versatile PoE controller suitable for multiple applications. It is primarily used in applications such as industry, building automation, and powering up remote equipment. It is also commonly used in telecommunications networks as a powerful and reliable means of providing power and control to remote hardware. Additionally, it can be used in consumer electronics, automotives, and power-hungry consumer and industrial applications.

The working principle of the PD69008 is simple. When the Host device requests power, the Controller supplies the power to the Host by turning on the internal power MOSFET. The Controller then monitors the current flowing in the power line and will adjust the output current as needed. As the current level increases, the internal thermal protection circuit will detect when the voltage level reaches the specified limit and will turn off the power MOSFET to prevent over-powering. The PD69008 also supports remote monitoring, allowing users to monitor the power levels of connected devices from a distance.

The PD69008 is an innovative and efficient PoE Controller, offering users a wide range of features and performance. The device provides integrated safeguards, support for multiple power levels, and remote monitoring, allowing users to safely and securely power up remote devices while receiving valuable diagnostics and information.
