Описание

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 I²C control for precision monitoring and intelligent power management.

• Pin-out enables two-layer PCB
• Kelvin current sensing
• 4-point Detection
• Automatic mode-as shipped
• No external terminal setting required
• No initial I²C communication required
• Semi-automatic mode-set by I2C command
• Continuous identification and classification
• Fast-port shutdown input
• Operates best when used in conjunction with system reference code
• Green product and no Sb/Br
