Microsemi has the broadest Power over Ethernet (PoE) product line in the industry, including PoE PD IC's, PoE PSE IC's, Midspans and Test Equipment. The PD chip product line includes PD chips with and without integrated PWM controllers, which can be used as a compact way to convert PoE input power to one or more output voltages in a Powered Device. When an external isolated controller is employed, the customer can benefit from either a lower cost implementation, using a non Synchronous Flyback controller like the IPS18I.


Microsemi is the pioneer of Power over Ethernet (PoE), the only supplier of PoE PD IC's, PSE IC's, Midspans / Injectors and test Equipment. Microsemi's PSE IC's product line is the broadest in the market with IC's featuring from 1 to 12 ports, and modules of up to 24 ports. Microsemi's PSE IC's can deliver up to 95W over a single Category 5 cable.

PoE Midspans, PoE Injectors & PoE Switches

Microsemi Power Over Ethernet (PoE) switches, PoE midspans and PoE injectors offer industry leading solutions for any PoE requirement. Our PoE systems portfolio enables delivery of up to 95 W of flexible and reliable power over Ethernet to WLAN access points, VoIP phones, IP cameras, thin/zero clients and other PoE powered devices. Microsemi is an innovator and thought leader in PoE technology and systems, as well as a major source of IEEE 802.3af, IEEE 802.3at, IEEE 802.3bt and HDBaseT standards.
