Power over Ethernet (PoE) Controllers have been quickly gaining popularity as an all-in-one, cost-effective solution for managing and controlling power to peripheral devices. The NCP1080DER2G from ON Semiconductor is an example of a multi-function PoE controller that is designed to dramatically reduce circuit complexity and save space in embedded systems.

This integrated device is made up of an integrated, monolithic PoE controller with four channels capable of sourcing and sinking up to 25 Watts, a Type 1 and Type 2 PoE controller with support for both IEEE 802.3bi and 802.3at standards, as well as a PD interface connected to an auxilliary power supply. It is ideal for applications such as PoE switches, WiFi access points and IP cameras which require a high density of disconnected network cables.

NCP1080DER2G features an integrated DC-DC converter to provide the power supply for each channel, as well as complete fault protection, temperature monitoring and advanced diagnostic functions.

The DC-DC converter supports a wide range of output voltages from 6 V to 18V, enabling the NCP1080DER2G to support a wide variety of system configurations and applications. The PoE controller also provides remote current monitoring per port and sophisticated Power Management Interface (PMI) support. The PMI protocol allows for communication between the module and the host system for monitoring and controlling parameters such as power, current, voltage, and temperature.

The device also includes an integrated Ethernet Transceiver (ETHER) interface. This allows for access to multiple Ethernet networks, and enables communication with the Power System Management Engine (PSME) over the ETHER interface. The PSME is responsible for the coordination and control of the Power Delivery and Management within the system. It enables the system to remotely monitor and control the NCP1080DER2G along with its Peripheral devices.

The NCP1080DER2G is designed to reduce bill of material costs and system complexity. It offers advanced safety and test feature support, such as loop-back detection, overload protection, and soft start. It is also designed to optimize system level electromagnetic compatibility (EMC) and thermal performance by providing multiple EMC filtering and advanced testing features. In addition, the device requires minimal power allocation and offers low-power standby modes.

By providing an integrated solution for power delivery and management, the NCP1080DER2G simplifies system designs with fewer external components required. This reduces complexity and provides key benefits such as increased system reliability, lower cost, and improved performance. This make this particular device an ideal solution for a variety of applications such as WiFi access points, IP cameras, and LTE base stations.
