MP8004GQW-P Integrated Circuits (ICs)

Power Over Ethernet (PoE) Controllers are a type of PMIC that are used to provide a power source to remote devices. The MP8004GQW-P is an integrated PoE controller designed by MPS to enable quick and efficient implementation of IEEE 802.3af-compliant PoE systems. It offers power subsystems with a single solution, allowing for consistent output voltage and current monitoring. It also offers integrated global standard communication protocols, making it widely applicable and reducing design time and effort in development.

The MP8004GQW-P suits a wide range of applications due to its many features. It is widely used in IP cameras, IP phones, wireless access points, and industrial/building automation systems and offers full system protection with thermal and power limiting. The MP8004GQW-P offers up to 720 m**A of power, providing power to the ethernet devices even in the remote area. It supports two ports of 10/100/1000BASE-T, with wire speed switching and 500 Mbps full-duplex forwarding. It offers up to 20 watts of power output, extended range transmission up to 100 meters, and can work with both managed and unmanaged PoE switches.

The working principle of the MP8004GQW-P is based on the IEEE 802.3af standard. It uses two wires, positive and negative, to transmit and receive data, and a third wire to transmit and receive power to and from the device. The signal and power are transmitted at different frequencies and effectively separated by a signal and power separation circuit, with the MP8004GQW-P acting as a controller that monitors the performance of the PoE system. It monitors and controls the output voltage and current to ensure consistent performance, and also provides system protection such as over-current, over-voltage and over-temperature protection.

The MP8004GQW-P PoE controller is a powerful and versatile device for implementing advanced PoE systems. It reduces development time and effort, is widely applicable, and provides system protection. With its integrated communication protocols and powerful features, the MP8004GQW-P makes it a great choice for PoE system implementation.
