TPS23861EVM-612 Evaluation Module for Quad IEEE 802.3at PoE PSE Controller


Order now


This easy-to-use design can be easily multiplied to 8-, 12-, 16-port and so on, while offering the industry’s best interoperability as well as a double sided PCB design.

Applications include Ethernet switch, surveillance Network Video Recorder (NVR), and small home/office routers.

The full PoE ecosystem includes the following optional companion tools:


  • Motherboard/daughterboard configuration supporting 4x type 2 (30W) ports and 2x 4 pair ports (60W).
  • TPS23861EVM-612 accepts MSP-EXP430G2 (MSP430 LaunchPad) EVM for power managing the TPS23861s. Basic power manager firmware is available for the MSP430 upon request.
  • TPS23861EVM-612 interface to USB-TO-GPIO and PC using PI-Commander GUI.
  • Default mode is Auto mode (meaning no host control is required)
  • Multiple PD loads available.
