Demonstration circuit 1814A features the LTC4274A, single port power sourcing equipment (PSE) controller, capable of delivering up to 90W of LTPoE++™ power to a compatible LTPoE++ powered device (PD). A proprietary detection/classification scheme allows mutual identification between an LTPoE++ PSE and LTPoE++ PD while remaining compatible and interoperable with existing Type 1 (13W) and Type 2 (25.5W) PDs. The LTC4274A feature set is a superset of the popular LTC4274. These PSE controllers utilize low RON external MOSFETs and 0.25Ω sense resistors which are especially important at the LTPoE++ current levels to maintain the lowest possible heat dissipation.
