Solid State Relays Cut ON Resistance By 50 Percent
January 3, 2008 8:21 am | Stmicroelectronics | Product Releases | CommentsSTMicroelectronics introduced a quad high-side intelligent power switch (IPS) -- the VNI4140K -- which is produced using the latest generation of ST’s VIPower technology to achieve a 50 percent saving in Rds(on) compared to earlier devices with the same die size, officials said. The reduction in on-resistance and quiescent current saves energy through lower losses. IPS devices integrate a logic interface, drivers and protection circuits on the same chip as a power stage

In line-operated systems with power levels from 75W to 1 kW and above, the UCC28070 helps reduce total harmonic distortion, allowing systems to maximize usable outlet power and accommodate extreme variations and disturbances
Hot-Swap Inverter Modules Provide up to 1500VA/1200W
January 3, 2008 6:32 am | Product Releases | CommentsUNIPOWER announced a series of hot-swap, high power density telecom inverters. The INV1000 Series are 1000VA/800W and 1500VA/1200W sine wave inverter modules which operate from a 48V DC input and provide either a 115V AC or 230V AC nominal output.
Military and Aerospace Systems Still Rely on Proven COTS Technology
January 3, 2008 5:55 am | by Doug Patterson, VP-Worldwide Sales & Marketing; Aitech Defense Systems Inc. | Articles | CommentsBecause of its inherent benefits including decreases to development times and increases in component compatibility, COTS (commercial-off-the-shelf) has been adopted by a vast number of industries, including the aerospace, military and space exploration markets. Most embedded systems within aerospace and military applications perform a function in some way related to mission-critical operation of the larger system and/or platform, making performance, reliability and functionality imperative to the design and manufacture of the embedded computing system. These systems must therefore operate flawlessly in very specific and defined ways while exposed to extreme environments, including high shock and vibration resistance, wide, dynamic temperature ranges, high humidity (or immersion), and the absolute vacuum of deep space.
Demystifying ZigBee and 802.15.4
January 3, 2008 4:58 am | by John Schwartz, Digi International | Articles | CommentsIn today’s world, wireless networks are becoming more ubiquitous, and they are implemented using a variety of protocols that are specifically designed for radio frequency systems. Some protocols that are in use are proprietary to individual vendors, while others are industry standards. Recently, a lot of attention has been given to 802.15.4 and ZigBee, but there is still some ambiguity as to what is different about 802.15.4 and ZigBee and what kind of networks or systems would benefit from these particular protocols.
The next great read?
January 3, 2008 4:01 am | by Chris Warner, Executive Editor | Articles | CommentsIf you got a head start on your holiday shopping in the days before Thanksgiving, you were greeted at Amazon.com with a message by founder and CEO Jeff Bezos announcing the release of Kindle, the company’s handheld e-book reading device. I have to admit, when a colleague first told me about Kindle, I reacted with a great big yawn.
Three-Phase BLDC MOSFET Pre-Driver Controller ICs
January 2, 2008 10:24 am | Product Releases | CommentsAllegro MicroSystems introduced two automotive grade (temperature and voltage rated) three phase BLDC motor controller integrated circuits.

10 Tips Make Embedded-System Code Easy to Maintain
January 2, 2008 9:18 am | by Timothy Stapko, Digi International | Articles | CommentsIn the rush to get a product out the door, programmers often ignore code maintenance — a key aspect of application development. For applications with short lives, this rush may not pose a significant problem because once deployed, no one will touch the code again. Embedded systems applications, however, may have lives that span decades, and early coding mistakes can result in significant bug-fix and update costs later on.
