PD69208M

PoE PSE Manager

Introduction

Microchip's PD69208T4, PD69204T4, and PD69208M Power over Ethernet (PoE) manager ICs integrate power,

analog, and state-of-the-art logic into a single 8 mm × 8 mm, 56-pin, plastic QFN package. The device is used in

conjunction with a Microchip PSE controller or an Ethernet switch processor from a supported third-party vendor to

provide an IEEE^®802.3af/at/bt or Power over HDBase (PoH) Power Sourcing Equipment (PSE) solution.
