Description

Linear Technology’s Power over Ethernet (PoE) range of products include power sourcing equipment as well as power device controllers intended to support different power levels such as IEEE PoE, IEEE PoE+, and Linear Technology LTPoE++ standard.

This technology eliminates power cables and AC outlet installations as it enables the transfer as well as management of power between PSEs and PDs through the use of cheap Ethernet cables. In order to minimize heat dissipation and bring power efficiency to it's maximum these PSE and PD controllers use external MOSFETs and sense resistors in all appropriate situations. In addition they meet the IEC61000 cable discharge requirements and come equipped with over temperature protection as well as a robust cable discharge protection.
