TPS23861PW, POE контроллер, 57В/ 7мА, 17.5В пороговое значение блокировки питания при ПН, TSSOP-28

The TPS23861PW is a quad IEEE 802.3at Power-Over-Ethernet PSE Controller features an easy-to-use flexible IEEE802.3at PSE solution. As shipped, it automatically manages four 802.3at ports without the need for any external control. It automatically detects powered devices (PDs) that have a valid signature, determines power requirements according to classification and applies power. Two-event classification is supported for type-2 PDs. It supports DC disconnection and the external FET architecture allows designers to balance size, efficiency and solution cost requirements. The unique pin-out enables 2-layer PCB designs via logical grouping and clear upper and lower differentiation of I2C and power pins. This delivers best-in-class thermal performance, Kelvin accuracy and low-build cost. In addition to automatic operation, it supports semi-auto mode via I?C control for precision monitoring and intelligent power management.
