Keywords:power sourcing equipment? PoE? connectivity?

Microsemi Corp. launches two Power Sourcing Equipment (PSE) PoE managers for commercial and industrial applications. The 4-port PD69104 and 8-port PD69108 support the high currents required by PoE Plus and HDBaseT. They come in a small factor and offer low power dissipation, making them suitable for video screen phones, WiMAX transmitters, pan-tilt-zoom cameras, thin-clients and laptops.

The devices feature internal power MOSFETs, enabling switch manufacturers to build switches that fully comply with IEEE802.3-2009 specifications, driving 30W over 2-pairs or 60W over 4-pairs.

The PD69104 and PD69108 come in a 48-pin QFN 8 x 8mm package, and are sampling now with volume production in Q2 2011.
