Overview

TIDA-00465 is an application using TPS23861 as a single port, type 2, PoE auto-mode PSE in a small form factor. The design will inject power onto any Ethernet cable for PoE powered loads up to 30W.

Features
  • TPS23861 IEEE 802.3at PSE Controller
  • Single Port 30W PoE Injector
  • Auto Detection and Classification of PD
  • Auto Turn on and Disconnect of PD
  • Requires only 48VDC, 40W AC-DC Adapter

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
