Maxim's IEEE® 802.3af/at-compliant products for power-sourcing equipment (PSE) and powered devices (PDs) provide an end-to-end PoE solution. Besides meeting the IEEE standard and ensuring interoperability, our PSE products are rated for 80V (absolute maximum rating). PD products are rated for 100V to ensure robustness. Some applications require power levels above the standard (PoE+). Maxim also offers PSE and PD solutions that provide up to 70W.
