New Controller IC and Plug-in Power Module Simplify Design and Increase Adoption for Ethernet-Powered AppliancesMay 17, 2004 - Texas Instruments Incorporated announced a versatile new integrated circuit (IC) controller and the industry's first Power-over-Ethernet plug-in power module that reduces design time and eases implementation of Ethernet-powered industrial and commercial devices such as WLAN access points, IP phones, security and point-of-sale systems.
First Complete Power-over-Ethernet Plug-in Module
Realizing time to market is critical, TI also announced the industry's first, fully IEEE 802.3af-compliant plug-in power module for Ethernet-powered devices. The PTB48540 module significantly reduces time to market for designers of specialized, Ethernet-powered IP phone consoles, security systems, card readers, point-of-sale terminals or other systems that need to quickly detect, classify and deliver up to 10 watts of DC power. Requiring only a small external Power-over-Ethernet isolation transformer, the low-profile module (41 mm x 38 mm x 8.5 mm) provides a complete power solution for powered devices. TI's TPS2375 controller sits inside the module, as well as an electro-magnetic interference (EMI)/input voltage transient filter, and both data and spare line bridge networks. The module is available in 3.3-V, 5-V or 12-V outputs with through-hole or surface mount device (SMD) mounting options. For more technical information on the PTB48540 plug-in module, see www.ti.com/sc04104b.
The TPS2375 powered device controller and the PTB48540 plug-in module are available in volume today from TI and its authorized distributors. The TPS2375 is packaged in an 8-pin (SOIC) or 8-pin thin shrink small outline package (TSSOP), and the PTB48540 comes in a 13-pin, double-sided, through-hole or surface-mount package. Suggested resale pricing is $1.25 each for the TPS2375 in quantities of 1,000 units, and $26 for the PTB48540 in quantities of 1,000.
