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