| | International Rectifier Introduces 100V-Rated Integrated MOSFET
Solution for PoE Applications Slashing Footprint Up To 80% | | EL SEGUNDO, Calif. —
International Rectifier, IR® introduced the IRF4000, a 100V-rated device integrating four HEXFET® MOSFETs into a
single Power MLP package for Power-over-Ethernet (PoE) applications. The new device complies to the IEEE 802.3af
specification for networking and communications infrastructure systems, such as Ethernet switches, routers and hubs,
delivering up to 15W per port, replacing four individual SOT-223-packaged MOSFETs. The reduced footprint equates to
a space savings of up to 80%, or three square inches of circuit board area in a typical 48-port board. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:49 | |
| | | Microchip Technology Announces Stand-Alone Analog Front End for
Wireless Authentication Applications | | CHANDLER, Ariz. — Microchip Technology Inc. announced
its first stand-alone, analog front end (AFE) for smart, low frequency (125 kHz typical) wireless authentication
applications. The MCP2030 device is a 3-channel transponder AFE that provides programmable antenna tuning and
best-in-industry adjustable modulation depth that runs as low as 8 percent. The MCP2030 AFE is ideal for
passive-keyless-entry, tire pressure monitoring systems (TPMS), data acquisition and other wireless authentication
applications. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:45 | |

| New Input-Current-Limited Battery Charger with Integrated 3.3V LDO
Offers Most Complete and Cost-Effective Solution | | SUNNYVALE, CA- -Maxim Integrated
Products introduces the MAX8730, a highly integrated, accurate, and low-cost battery-charger IC. The MAX8730
charges three to four lithium-ion (Li+) cells in series at charge currents greater than 3.5A. Analog inputs control
input current limit, charge current, and voltage. An integrated 3.3V LDO supplies over 20mA current to any external
circuitry or ICs, such as a keyboard controller. Three monitoring outputs simplify design, and save external
component cost and board space. Two analog outputs are available for charge current and input current; a digital
output is used to detect AC-adapter presence. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:44 | |
| | | NI Introduces High-Voltage Mechanical Relay Digital I/O PC Plug-In
Devices | | National Instruments today announced the expansion of its data acquisition
offerings with the addition of two new Underwriters Laboratories (UL) listed high-voltage plug-in mechanical relay
devices. NI, a worldwide leader in data acquisition with more than 6 million data acquisition channels sold in the
last year, continues to make it easier for engineers to develop measurement and control systems while integrating
them into a common programming environment. The new National Instruments PCI-6521, PXI-6521 and PCI-6520 industrial
digital I/O devices offer engineers a low-cost alternative for applications requiring up to 150 VAC/VDC switching
capabilities. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:43 | |

| TI INTRODUCES PRECISION, MICRO-POWER OP AMPS FOR BATTERY-POWERED
APPLICATIONS | | DALLAS - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a
new family of precision, micro-power operational amplifiers (op amps) from the company's Burr-Brown product line.
The OPA379 family operates within a 1.8V to 5.5V supply voltage range and features high performance single-supply
operation, very low quiescent current (2.9uA) and low noise (80nV/rtHz) relative to the quiescent current. The
micro-size packages make the devices ideal for battery-powered applications. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:40 | |
