150V Low IQ Inverting Synchronous DC/DC Controller Uses a Single Inductor; Has Ground-Referenced Controls

May 25, 2016  by  

linear 2-25-16Linear Technology Corporation introduced the LTC3896, a high voltage inverting switching regulator controller that drives an all N-channel synchronous power MOSFET stage.

Most low to medium power inverting DC/DC converters utilize a coupled inductor or transformer. However, the LTC3896 uses only a single inductor and converts a 4V to (150V – |VOUT–|) positive input voltage to a regulated negative output voltage from –60V to –0.8V at output currents up to 15 amps. Efficiencies are as high as 96%, ideal for transportation, industrial, telecom and power distribution applications.

Mentor Graphics MicReD® 600A Tests EV/HEV Power Electronics Reliability During Power Cycling

May 23, 2016  by  

Mentor Graphics MicReD Power Tester 600AMentor Graphics introduced a MicReD® 600A that tests electric and hybrid vehicle (EV/HEV) power electronics reliability during power cycling. The MicReD Power Tester 600A allows engineers to test power electronics – such as insulated gate bipolar transistors, IGBTs, MOSFETs, transistors and chargers – for mission-critical thermal reliability and lifecycle performance.

The ever wider adoption of electric and hybrid cars has created a specific need for this solution, since thermal reliability issues can result in EV/HEV recalls.

Automotive Security Threats and Recommendations

May 17, 2016  by  

Mike Borza synopsysMike Borza, member of the technical staff for Synopsys security IP, reviews key security issues that design teams must consider when developing IP for automotive applications.

Every aspect of the automobile is designed to be more connected, requiring subsystem and SoC designers to expand their scope of safety measures beyond the traditional steps taken to ensure physical safety. New connected cars offer hackers multiple opportunities to breach security, from body and panel subsystems to ECUs, Advanced Driver Assistance Systems (ADAS) and infotainment platforms. Understanding the threats, system vulnerabilities and emerging standards will help designers to develop a continuous, appropriate response to the constantly evolving threat environment.

Panasonic Delivers Thermal Sensing Solutions With Grid-EYE Infrared Array Sensor

March 25, 2016  by  

panasonic 3-24-16Panasonic Corporation has developed a thermal sensation estimation method* using the infrared array sensor Grid-EYE.

Based on the results of estimations, the company has started to deliver high-precision thermal sensing solutions that recognize thermal comfort for people.

The solution will be effective in homes and vehicles, among other applications.

The thermal sensation estimation method recognizes the human sensations of hot and cold by calculating heat loss based on the difference between human surface temperature and ambient temperature. The thermal sensing solutions Panasonic provides are a super-resolution algorithm using Grid-EYE, an infrared array sensor, to measure the temperature distribution in detail and detect objects, thereby achieving air conditioning suitable for sensed temperature by combining the obtained data and thermal sensation estimation method. In addition, Panasonic has developed unique software that maximizes performance and offer it in solutions for various applications.

Texas Instruments (TI) (NASDAQ: TXN) introduced a 2.2-MHz, dual-channel synchronous buck converter with features designed to significantly reduce electromagnetic interference (EMI) and high-frequency noise in high-voltage DC/DC step-down applications such as automotive infotainment and high-end cluster power-supply systems.

The LM5140-Q1 controller includes dual outputs with phase interleaving and is offered in wettable flank packaging that speeds manufacturing. Together with TI’s WEBENCH® Automotive Design tool, the LM5140-Q1 enables engineers to get their automotive designs to market faster. For more information, samples and an evaluation module, see www.ti.com/lm5140q1-pr.

The A6985F and A6986F, Two New Efficient Synchronous DC/DC Buck Converters for Automotive Applications

Fulvio Ottavio Lissoni, DC-DC Converters Application Manager


The latest car generation includes more and more functionalities in body control, car infotainment / connectivity (including Advanced driver assistance systems — ADAS), and clusters. For example, onboard car multimedia is required to be compatible with everyday portable equipment and to play audio/video files from external storage media. Navigation and ADAS are options widely diffused in the automotive market.

Body control applications that are always connected to the battery require high efficiency in light load conditions to limit the overall current consumption, below 100 A typically, and so preserve the battery charge while the engine is off.

Managing real-time platforms for ADAS and automated driving

By Dr. Kai Richter, Maurice Sebastian, Sean Whitty and Jonas Diemer of Symtavision (now part of Luxoft)
The move towards ADAS and automated driving marks a milestone in the history of the automotive industry, which possibly (some say most likely) will revolutionize passenger traffic worldwide. From a technical perspective, we are also seeing significant changes being caused by the arrival of new components and by totally new system and software architectures. As a consequence, new business models and new providers are beginning to emerge particularly in the areas of hardware/software and system integration.
