Overview

This reference design is fully autonomous IEEE802.3at, Type-2 (30 W) Power-over-Ethernet (PoE) 4-port power sourcing equipment (PSE). An additional configuration of two non-standard, high-power ports (<60 W) is provided. Both configurations support gigabit Ethernet data pass through in 1000BASE-T ports.

This reference design is made up of two boards:

  • Motherboard (TPS23861EVM-612)
  • Daughter board (TPS23861EVM-613)

The daughter board features two TPS23861 IEEE 802.3at PoE PSE controller devices. The motherboard provides a multi-port base platform interface for the daughter board. Additionally, the motherboard provides interfaces for two optional boards: MSP-EXP430G2 LaunchPad™ (if custom power management programmability is desired) and USB-to-GPIO interface adapter (if PC GUI-based power management configuration is desired).

This reference design has undergone exhaustive PoE testing and passes all industry-recognized conformance/interoperability test suites allowing customers to copy/paste the design without concern. The 2-layer PCB, daughter card, design delivers all of this on a low-cost platform.

Features
  • TPS23861 PSE devices default to full autonomous mode so no digital interface is required
  • Passes UNH-IOL PoE conformance/interoperability and SIFOs Type 1/Type 2 test suites
  • Four IEEE802.3at, Type 2 (30 W) ports and two non-standard, high power (<60 W) ports supported
  • Entire design is powered by a single DC supply. Logic power is delivered by an on board 3.3-V regulator (LM5007)
  • I2C interface allows programming via PC-based-GUI, or microcontroller-based code
  • Port ON status LEDs provides simple status indication in fully autonomous mode
