PD69200

PoE PSE Controller

Introduction

The Microchip family of PSE controllers include the PD69200, PD69210, and PD69220 devices. The PD69200

Microchip SAM D21 family. The PD69200 and PD69220 are pin compatible with an identical feature set. The

PD69200 is available for existing designs. The PD69210 and PS69220 are recommended for all new designs.

When paired with the Microchip PD69208T4, PD69204T4, or PD69208M Managers, the PD69200 controller is part of

a Power over Ethernet Power Source 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.

The PD69200 is available in a 32-pin, 5 mm x 5 mm QFN package.
