Available in a variety of packaging including TO-220, D2PAK, TO-262, and 7-lead D2PAK, logic-level gate-drive trench HEXFET power MOSFETs from International Rectifier have a package current rating of up to 195 A.
Researchers at MIT have developed a new system that may provide a cheaper and more efficient way to track motion. The system, called Second Skin, could be a cheaper alternative for creating special effects for movies.
Conventional wisdom says that “early adopters” eventually bring new technologies into the mainstream. Thus, the effort to promote solid state lighting (SSL) has ample historical precedence. Back in the late 70’s, 80’s, and 90’s an epic battle was waged between Video Home System (VHS) and Betamax (Beta). One can draw lessons from the eponymous “videotape format war”—specifically, why technologies catch on (while others fade away)
Designed for applications with high-power inductive loads, Allegro’s A4940 full-bridge MOSFET pre-driver IC incorporates fault diagnostics and reporting functionality. With an operating voltage from 5.5 V to 50.0 V, the 24-pin TSSOP-packaged device has a bootstrap charge management system that ensures the bootstrap capacitor is always sufficiently charged to supply the high-side gate drive circuit.
Motorola Inc. defeated low expectations Thursday, posting a smaller first-quarter loss than Wall Street had expected and regaining its position as the world's fourth-largest maker of cell phones. Investors were largely unimpressed, and analysts pointed to deterioration in the Motorola units that have been propping up the dismally performing cell phone operations.
Electronic health records need a nudge from the government if the technology is to become widespread, the nation's new health information technology czar said on Thursday. "It is clear that this field has not advanced (enough) when left exclusively to the private sector so there is a public role," said Dr. David Blumenthal, head of the Department of Health and Human Services' Office of the National Coordinator for Health Information Technology.
Scientists have made the fastest camera ever. It can take 6.1 million pictures in a single second, at a shutter speed of 440 trillionths of a second. Light itself moves just a fraction of a centimeter in that time.
Chrysler will file for bankruptcy after talks with a small group of creditors crumbled just a day before a government deadline for the automaker to come up with a restructuring plan, two administration officials said Thursday.
Apple Inc is hiring new employees from the semiconductor industry and is building the capability to design its own chips, the Wall Street Journal reported on Wednesday. The iPhone and iPod maker hopes its efforts will lead to new features for its devices and enable it to share fewer details about it plans with outside chip vendors, the report said, citing people familiar with Apple's plans.
As car companies lined up in Washington, DC last November for the first round of federal bailout money - in San Francisco we announced another way - our comprehensive plan to make the San Francisco Bay Area the "Electric Vehicle (EV) Capital of the US."
Hoping to bridge the gap between airplanes and rocketships, the U.S. military is preparing to test an experimental aircraft that can fly more than six times faster than the speed of sound on ordinary jet fuel.
Automated Storage and Retrieval Systems (ASRS) are at the heart of any fully automated warehousing system. As in all automated solutions, users demand nearly perfect, (i.e., 100%) availability and exceptionally fast operation at the lowest possible price point. While the raw speed of an ASRS along each axis of motion is limited by the selected drives’ components, modern sensor technology
Measuring 2.2 mm x 2.6 mm x 0.9 mm, the T5300 digital pressure sensor from EPCOS is presented as the most compact packaged sensor of its kind. Designed for measuring absolute pressures from 300 to 1200 mbar, the sensor provides 14-bit resolution at the serial digital interface.
Provided in a 5 mm x 3.2 mm package, the XpressO FVXO-LC52 LVDS VCXO from Fox has an operating frequency range from 0.75 MHz through 1.0 GHz. The configurable-frequency device uses a third-order Delta Sigma Modulator to reduce noise levels comparable to traditional bulk-quartz and SAW oscillators.
Since their introduction in the US in late 1999, hybrid cars have been repeatedly dismissed as a “bridge technology”—a euphemism for a short-lived second-rate technology that briefly serves a purpose until it can be replaced with something better and longer lasting. But in recent statements coming within days of one another, executives from Honda and Nissan are reconsidering the role that hybrids will play in the coming decades.
