PD77728 8-Port PoE PSE Controller/Manager

Microchip Technology PD77728 8-Port PoE PSE Controller/Manager is part of Microchip’s seventh-generation IEEE® 802.3bt-compliant Power over Ethernet (PoE) Power Sourcing Equipment (PSE) family. This device is a fully integrated 8-port PoE controller, and PoE manager with integrated Field Effect Transistor (FET) switches and current sense resistors. Up to 12x devices can be cascaded to provide 48x 4-pair ports. According to IEEE, the device supports PoE Powered Device (PD) detection, classification, power-up, and protection, as well as legacy/pre-standard PD detection. The Microchip Technology PD77728 provides real-time protection through overload, under-load, over-voltage, over-temperature, short-circuit, and enables operation in standalone mode. The device is available in a 56-pin 8mm × 8mm QFN package.
