150-mA synchronous DC/DC regulators optimize light-load efficiency for factory automation and automotive applications
Texas Instruments (TI) (NASDAQ: TXN) introduced two 65-V, 150-mA synchronous DC/DC buck converters with what the company said is the industry’s lowest 10.5-uA quiescent current (IQ) for powering factory automation and automotive sensor applications requiring high efficiency.
The industrial-grade LM5165 and automotive-grade LM5165-Q1 micro-power step-down regulators feature a wide input voltage (VIN) range and dual control modes for optimizing efficiency and printed circuit board (PCB) area. By using the regulators together with TI’s WEBENCH® Power Design tool, engineers can get their factory and process automation designs to market faster. For more information, samples and an evaluation module, see www.ti.com/lm5165-pr.
SMT power inductors from TT Electronics support 180°C high temperature operation in automotive applications
TT Electronics launched a range of surface mount (SMT) power inductors for use in high temperature, high power, automotive applications. The HA72T-06 series inductors meet the growing automotive market’s demand for certified, high power inductors for high efficiency DC-DC converter deployment using high switching frequencies up to 3Mhz as well for as EMI and low pass DC ripple filters in high temperature environments.
With increased connectivity of applications and devices,OEMS in the automotive and other industries are demanding new assurance that software has been developed to the highest security standards.
To help customers guard against new risks and create safe and secure code, LDRA has integrated comprehensive support of the new security-focused rules announced by MISRA into LDRA’s MISRA coding standards compliance offerings.
MISRA Adds 14 New Security Guidelines to Help Eliminate Software Vulnerabilities
Provides Improved Fuel Economy, Fewer Parts, Lower Weight and Reduced Costs
Better fuel efficiency. Fewer parts. Lighter weight. Lower costs. Reduced noise, vibration and harshness (NVH). Dayco’s newest innovation, the Dayco Vacuum Generation System, which will go into full production with a major automaker in mid-2016, continues that tradition.
The Dayco Vacuum Generation System replaces costly, heavy, fuel-consuming mechanical and electrical vacuum pumps found on many of today’s engines. Automakers will benefit from reduced weight and decreased system cost, and automakers and consumers can enjoy increased fuel economy.

When developing a key structural component of a vehicle such as an engine, it is routine for an automotive manufacturer to use a standard testing framework (an engine test stand) to develop, characterize, and test those engines.
For example, in the development phase most automobile OEMs are interested in designing engines with optimal fuel efficiency, durability, and that are in compliance with all relevant legislation on emissions, etc. An engine test stand allows the engine to operate in many different modes and offers measurement, control, and recording of the associated physical variables – a process required to catalog the many parameters that affect the engine’s design and performance.
Latest DSP quadruples neural network performance capability compared to previous-generation Vision DSP
Cadence Design Systems, Inc. (NASDAQ: CDNS) announced the Cadence® Tensilica® Vision P6 digital signal processor (DSP), Cadence’s highest-performing vision/imaging processor, which extends the Tensilica product portfolio further into fast-growing vision/deep learning applications areas.
New instructions, increased math throughput and other enhancements set a new standard in imaging and computer vision benchmarks, increasing performance by up to 4X compared to the Tensilica Vision P5 DSP.
Joyson and Preh create a global player for car infotainment, connectivity and telematics.
The acquisition of TechniSat Automotive by the automotive supplier Preh, a member of the Joyson Group, has taken effect following approval by the relevant trade authorities. The Chinese Ningbo Joyson Electronic Corp. and its German subsidiary Preh Holding GmbH respectively hold 50 % of the new company which will now operate as “Preh Car Connect GmbH”.
Bosch is developing connected solutions in the Swedish city of Lund. The company’s first engineering location in Scandinavia already has 50 Bosch experts on board. They are working on new software and hardware in areas such as vehicle connectivity, automotive security systems, and motorized two-wheelers. In addition, they are developing cross-domain solutions for connecting mobility with, for example, energy and building technology over the IoT.
Linear Technology Corporation introduced the LTC4380, an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems.
The LTC4380 replaces traditional shunt circuits composed of bulky inductors, capacitors, transient voltage suppressors (TVS), and fuses with a simple IC and series N-channel MOSFET solution, saving board space and enabling continuous operation through transient voltage or current surges. The LTC4380 protects downstream electronics from input overvoltage up to the MOSFET rating, while also protecting the power supply from output overload. Device current consumption is a mere 8µA in normal operation and 6µA in shutdown mode, prolonging battery run and standby time. The low current allows a large filtering resistor to the device supply pin, enabling operation through automotive cold crank and overvoltage transients above 100V.
Integration of Modelon’s OPTIMICA Compiler Toolkit will advance the Ricardo Software IGNITE product’s simulation speeds and capability – and offers the opportunity for future significant enhancements.
Ricardo Software announced a partnership that will deliver immediate benefits to users of its IGNITE complete vehicle system simulation product, and is also expected to enable significant future developments. In the upcoming 2016 product release, planned for May, IGNITE users will have instant access to Modelon’s OPTIMICA Compiler Toolkit, a Modelica and Functional Mock-up Interface (FMI) based computational platform for system design.
