Linear Technology 38V Synchronous Step-Down Controller with 24V Output Capability Draws Only 50µA in Standby
August 21, 2014 by John Day
Linear Technology Corporation introduces the LTC3807, a low quiescent current synchronous step-down DC/DC controller that draws only 50µA in standby mode with the output voltage in regulation.
The 4V to 38V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries.
The output voltage can be set from 0.8V to 24V at output currents up to 25 amps with efficiencies as high as 95%, making it well suited for automotive, heavy equipment, industrial and robotic applications.
Infineon Technologies and International Rectifier Corporation have signed a definitive agreement under which Infineon will acquire International Rectifier for $40 per share in an all-cash transaction valued at approximately $3 billion.
The acquisition combines two semiconductor companies with leadership positions in power management technology. By the integration of International Rectifier, Infineon complements its offerings and will be able to provide customers with an even broader range of innovative products and services. Infineon will also benefit significantly from greater economies of scale as well as a larger regional footprint.
ITS America Statement on U.S. DOT Advance Notice of Proposed Rulemaking on V2V Communication Technology
Intelligent Transportation Society of America (ITS America) President and CEO Scott Belcher made the following statement in response to the National Highway Traffic Safety Administration (NHTSA) release of an advance notice of proposed rulemaking (ANPRM) and supporting comprehensive research report on vehicle-to-vehicle (V2V) communication technology.
“We applaud the U.S. Department of Transportation for taking this significant step to dramatically reduce the number of lives lost in traffic and pedestrian crashes. Today’s report and advanced rulemaking announcement reinforces the real-world safety benefits reported by our members in the automotive and tech communities, that vehicle-to-vehicle communications technology represents the next giant leap in automotive and pedestrian safety.
Mentor Graphics Corporation announced a new version of the Mentor® Embedded Nucleus® real time operating system (RTOS) targeting high-performance, next-generation applications for connected embedded devices.
The Nucleus RTOS process model is expanded to include ARM® Cortex® M- based cores. For the first time, software developers can use a single embedded operating system to increase system reliability through memory partitioning for the entire spectrum of ARM cores, facilitating code reuse across an entire product family comprising low-end to high-end devices.
New in this release is a multicore framework to manage inter-process communication (IPC) and processor life cycle for complex heterogeneous system-on-chip (SoC) and enhanced Nucleus RTOS graphics capabilities with Imagination and Vivante GPU support.
NNG, Budapest-based developer of iGO Navigation software, acquired nfuzion, an American HMI prototyping company. The acquisition will allow NNG to broaden its presence in automotive on-board systems, including infotainment and HMI (human-machine interface).
nfuzion capabilities range from industrial and UI design to mechanical and electrical engineering. They bring 14 years of in-car entertainment knowledge to NNG, having worked with numerous international car brands, and give NNG a new range of tools, products, and consulting to utilize on future projects. NNG and nfuzion had previously worked together and expressed mutual interest in combining their efforts.
TI Introduces Ultra-Low Quiescent Current, High-Voltage LDOs for Direct-to-Battery Automotive Applications
Texas Instruments (TI) introduced 17 new AEC-Q100-qualified, high-voltage LDOs for automotive and industrial applications.
The new ultra-low quiescent current LDOs, including the TPS7A16xx-Q1 with 60-V input, TPS7A66xx-Q1 and TPS7B67xx families, and the TPS7B4250-Q1 LDO, support many applications that connect directly to a car or truck battery, such as cluster, power steering and infotainment systems, door modules and lighting controls.
For more information, to order samples or purchase evaluation modules for the new ultra-low quiescent current, high-voltage LDOs, visit www.ti.com/autoldo-pr.
Offered in a compact 28-pin package, with four digital inputs, this pre-driver IC provides a very flexible, inexpensive and space-saving solution for high current N-FET DC motors.
Though BLDC motors are now becoming increasingly commonplace, DC motors are still more cost effective in a broad spectrum of application areas, especially where the motor is not continuously running.

K2L GmbH & Co. & Co. KG announced its Automotive Test System (ATS), which is a singular hardware and software tool that supports all of the major automotive busses for all of the activities related to test and simulation, such as rest bus simulation, device simulation, testing during system development and rapid prototyping.
ATS also covers all of the requirements for conducting analysis and verification. By combining all of these functions and support for the CAN, LIN, FlexRay® and MOST® networks into one tool, ATS provides the most cost-effective and flexible option to the automotive industry. It also enables automated testing and any kind of simulation, helping to ensure quality from the earliest design stages.
Continental is putting together an international team of innovators from the IT and automotive industries who will focus on Intelligent Transportation Systems (ITS).
The new business unit, called “Continental Intelligent Transportation Systems, LLC”, will be headquartered in Silicon Valley and headed by Seval Oz, an expert in vehicle networking and automation. In her previous role she worked on Google’s self-driving car project.
“This step is an excellent example of our strategy to make the car an integral part of the ‘Internet of Everything’. Our key objectives include eliminating road accidents, minimizing energy consumption, maximizing comfort and usability of vehicles, and enabling them to exchange information with each other in real-time,” said Dr. Elmar Degenhart, Continental CEO.
