PoE Controller 24-Pin QFN EP T/R

Microsemi"s PD69101 is a single port, mixed-signal, high-voltage Power over Ethernet driver. The device is utilized in Ethernet switches and enables network devices to share power and data over the same cable. It enables detection of IEEE802.3af-2003 compliant PDs (Powered Devices) and IEEE802.3at High Power Devices, thus, ensuring safe power feeding and disconnection of ports with full digital control and a minimum of external components. Integrating power, analog and state of the art logic, the PD69101 device fits into a single 24-pin, plastic QFN package. A "plug and play" device, the PD69101 executes all real time functions as specified in the IEEE802.3af-2003 ("AF") and IEEE802.3at High Power ("AT") standards, including load detection, "AF" and "AT" classification, and using Multiple Classification Attempts (MCA). The chip includes built-in internal thermal protection. Two LEDs provide port state"s indication and port type (AF/AT).
