The TPS23861PWR is a Power over Ethernet (PoE) controller designed to manage four IEEE802.3at ports automatically, requiring no external control. It detects powered devices (PDs) with valid signatures, assesses their power needs based on classification, and applies power accordingly. The device supports two-event classification for type-2 PDs and features an external FET architecture that allows for flexibility in design, balancing size, efficiency, and cost. This controller operates in both automatic and semi-automatic modes, with the latter allowing for I¬=C control for enhanced monitoring and power management. It complies with the 400-ms T_PON specification in both modes. The TPS23861PWR is packaged in a 28-pin TSSOP format, with a body size of 9.8 mm x 6.6 mm, and operates over a temperature range of -40¬8C to 125¬8C. It is suitable for applications such as Ethernet switches, routers, surveillance systems, and PoE pass-through systems.
