TI Korea (CEO Kent Chon, www.ti.com/ww/kr ) August 20, 2014 – TI (CEO Kent Chon) has released a new 2-layer PoE PSE (power sourcing equipment) evaluation module and TI design based on the TPS23861 PoE controller to help simplify the design of rapidly growing Power over Ethernet (PoE) applications. This high-performance quad-port controller and reference design significantly reduces development time and costs for PoE-enabled network video recorders, IP phone switches, and wireless base stations.

Key Features and Advantages of PoE PSE Design
● Reduction in PoE Development Costs: The TPS23861 evaluation board mounts the relevant circuitry and two controllers on a 2-layer printed-circuit board, minimizing material and manufacturing costs that can arise from using multiple boards.
● Simple "Plug and Play" operation: The evaluation module can also be used in automatic mode without host control.
● IEEE Compatible: The TPS23861 has passed the test suites of the University of New Hampshire Interoperability Lab and SIFO.
● Thermal Design Flexibility: The TPS23861's power consumption does not exceed 400mW under any operating conditions, and the external FET usage method allows design engineers to select the FET best optimized to their desired requirements for size, cost, efficiency, and more.
● Enhanced Reliability: Prevents system damage by preventing startup errors with 4-point detection.

For custom power management programming and configuration, the TI-designed motherboard provides interfaces for two optional boards, the MSP-EXP430G2 LaunchPad™ and a USB-GPIO interface adapter, both of which are available for purchase at the TI eStore.

With its advanced semiconductor products and extensive system expertise, TI enables manufacturers to rapidly supply high-performance PoE products to end-product developers. As a founding member of the PoETec Consortium and the University of New Hampshire PoE Consortium, TI has played a key role in the IEEE 802.3bt tack force establishing high-power PoE standards. More details about TI's contribution to PoE innovation can be found on TI's PoE page or in the IEEE 802.3 series on the Power House blog.
