PD69210/PD69220

PoE PSE Controller

Introduction

The Microchip Generation 6 family of PSE controllers include the PD69210 and PD69220 devices. The PD69210 and

PD69220 controllers have an identical feature set and differ only in physical pinout. They are based on the Microchip

SAM D21 family. The PD69210 or PD69220 controllers are recommended for all new designs.

The PD69210 or PD69220 controllers when paired with the Microchip PD69208T4, PD69204T4, or PD69208M

managers are part of a Power over Ethernet Power Supplying Equipment (PSE) system. This system enables

designers to integrate enhanced mode PoE capabilities, as specified in IEEE

®

802.3af, IEEE 802.3at, IEEE 802.3bt,

and PoH standards, into an Ethernet switch. They support up to 48 4-pair or 2-pair logical ports.

Both controllers are available in a 32-pin, 5 mm × 5 mm QFN package.
