Precision Current Input With Well-Defined Current Limiting for Extreme Environment Applications
Posted in Briefs, TSP, Power Management, Sensors on Sunday, 01 February 2015
NASA’s Jet Propulsion Laboratory, Pasadena, California Wide temperature and extreme environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.

UltraCMOS®-based power management card
Peregrine Semiconductor Corp.
San Diego, CA
Selected for NASA Goddard Space Flight Center’s SpaceCube 2.0 Hybrid Science Data Processor, Peregrine’s UltraCMOS®-based power management solution is delivering uninterrupted high performance while meeting the radiation-hardened and extreme-temperature requirements on the International Space Station. The regulators feature integrated switches that help the design team meet its goals of delivering order-of-magnitude improvements in on-orbit computing performance over traditional flight computing systems.
PRODUCT OF THE MONTH: SP1012 Series TVS Diode Array
Posted in Products, Board-Level Electronics, Electronic Components, Electronics, Power Management on Sunday, 01 February 2015
Littelfuse, Inc., Chicago, IL, introduces the SP1012 Series TVS Diode Array (SPA® Diodes), a miniature, five-channel 6.5pF, 15kV bidirectional TVS array for general-purpose electrostatic discharge (ESD) protection. The SP1012 Series packs five ESD diodes in a 0402-size (0.94mm × 0.61mm) flipchip package that would normally contain only one, so it offers a 5x improvement over previous implementations.

Aircraft with Hybrid Engine Can Recharge in Flight
Posted in News, Aviation, Batteries, Power Management, Motors & Drives, Power Transmission on Wednesday, 21 January 2015
Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric propulsion system, where an electric motor and gas engine work together to drive the propeller. The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a gas-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
15 Questions to Ask About Circuit Protection for Wearable Electronics
Posted in Articles, Electronic Components, Power Management on Thursday, 01 January 2015
Have you attended an electronics or design tradeshow lately? Have you visited a big-box retailer or browsed an online electronics vendor? If so, you’ve probably seen many examples of wearable technology, including smart glasses, clothing, wristwear, footwear, neckwear, and headbands. Wearable computing is one of the hottest consumer electronics trends on the market, with global sales expected to grow from $14 billion in 2014 to over $70 billion in 2024, according to IDTechEx.
Hospital-Grade Standards for Power Cords and Other Power System Components for Global Markets
Posted in Features, Electronic Components, Power Management, Power Supplies, FDA Compliance/Regulatory Affairs on Thursday, 01 January 2015
While a number of countries have standards in regards to overall medical equipment, a few countries have related component requirements (e.g. plugs and cords). For the countries that do have hospital-grade or medical application standards on components, it is important to know what the requirements are so as to comply with that country or region’s rules.
