View All Parametrics

Advanced PoE PSE IC Solutions

Our PSE Integrated Circuits (ICs) portfolio is the broadest in the industry, offering solutions that deliver up to 90W over standard Ethernet infrastructure. These plug-and-play solutions make it easy for system developers to transition to the latest IEEE^® 802.3bt standard by enabling both pre-standard and IEEE-compliant PDs to receive up to 90W of power without changing existing switching or cabling.

As a long-time innovator in Power over Ethernet (PoE) technology, Microchip is the only supplier of PoE PSE ICs, PD ICs, midspans/injectors and test equipment.
