Part Number: TPS23861
Function: IEEE 802.3at Quad Port Power-over-Ethernet PSE Controller
Package: TSSOP 28 Pin Type
Manufacturer: Texas Instruments
The TPS23861 is 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.
The device 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.
The IC supports DC disconnection and the external FET architecture allows designers to balance size, efficiency and solution cost requirements.
