Microchip Technology EV65N25A Evaluation Board
Microchip Technology EV65N25A Evaluation Board is developed based on Microchip’s PD70288 Ideal Diode Bridge (IDB). The PD70288 device is part of the third-generation IEEE® 802.3bt compliant Power over Ethernet (PoE) Powered Devices (PD) family. PD70288 is a dual-active bridge with internal MOSFETs having a total path resistance of 140mΩ (typical) and is available in a 38-pin, 8mm x 8mm QFN package. The Microchip EV65N25A demonstrates a Single Signature Powered Device (SSPD) application. The board uses the PD70210AILQ, a PD front-end device, to support the detection, classification, and power-supplying phases on the 2/4 pairs. The board supports up to 90W output power when connected to a 4-pair PoE input. The output current should be limited to 1.5A when connected to a 2-pair PoE input.
