Texas Instruments Inc. (TI) has announced a couple of solutions to speed up design for the rapidly growing Power over Ethernet (PoE) applications. According to the company, the two-layer PoE power sourcing equipment (PSE) evaluation module and TI Design based on TI's TPS23861 PoE controller significantly reduce development time and cost when creating PoE-enabled network video recorders, IP phone switches and wireless base stations.

The TPS23861 evaluation board features two controllers with associated circuitry on a two-layer PCB, minimising material and build costs that often occur when using multiple boards. The evaluation module is also offered in auto mode, eliminating the need for host control. In addition, the TPS23861 passes the University of New Hampshire's Interoperability Lab and SIFO's test suites.

TPS23861

The TPS23861 consumption does not exceed 400mW in any operating condition. The external FET architecture allows the design engineer to select the FET that best meets size, cost, and efficiency requirements. The four-point detection feature avoids system damage by preventing erroneous start-up.

For custom power management programmability and configuration, the TI Design's motherboard provides interfaces for two optional boards, the MSP-EXP430G2 LaunchPad and USB-to-GPIO Interface Adapter, which are both available in the TI eStore.

Available in a 28-pin TSSOP package, the TPS23861 PoE PSE controller is priced at $3.40 each in 1,000-unit quantities. The TPS23861EVM-612 evaluation module is available for $299 and includes a downloadable PI Commander graphical user interface. A fully tested and proven TIDA-00290 PoE reference design with schematic, BOM and design files is also available for download.
