PD69104B1FILQ-TR, a fully integrated injection-based Power over Ethernet (PoE) controller, is specifically designed to control and manage the power delivered over Ethernet. It is used in the most advanced Power Sourcing Equipment (PSE) designs to provide both power and data, thus reducing complexity, board space, and cost. This controller is suitable for modern PoE applications that require complex power delivery such as IP phones, WiFi access points, and HD cameras.

The PD69104B1FILQ-TR is a unique controller, able to provide power in both IEEE 802.3af and 802.3at compatible modes and can handle four separate ports with different Classifications. It meets the full requirements of the PoE standards, providing a host of protection features such as Overload Protection (OLP), Current Limit(CL), Under Voltage Lock Out (UVPO), OverTemperature Protection (OTP), Short Circuit Protection (SCP), Loss of Synchronization (LOS), and Over Voltage Protection (OVP). It also has various optional featurese, such as GetLink and Port Enable Link, allowing for advanced customization. Additionally, the PD69104B1FILQ-TR is designed with a small form factor and operates in temperatures up to 105℃, enabling it to be used in cramped environments and physically demanding applications.

The PD69104B1FILQ-TR uses an injection-based control scheme that combines PWM or linear Vin control with a dynamic envelope tracking of the voltage and current. This method ensures stable power delivery under varying line and load conditions, while minimizing ripple/noise and maximizing efficiency. Furthermore, the controller has adjustable output voltage ranges, adjustable over current protection thresholds, under voltage lock out, and integrated sense resistor. This allows the PD69104B1FILQ-TR to meet specific application and customer requirements.

The PD69104B1FILQ-TR is reliable and simple to use, making it the ideal choice for power over Ethernet designs. It offers low power consumption and is designed to work in temperatures up to 105℃, making it the perfect choice for modern PoE applications. It provides protection features and adjustable parameters that allow the designer to customize the system to the specific application requirements, while maintaining full compliance to the IEEE 802.3af and 802.3at standards.
