Panasonic Corporation announced the development of gallium nitride (GaN) diodes that operate at a high current and are four times greater than that tolerated by conventional silicon carbide (SiC) diodes*1. They also operate at low voltages by virtue of their low turn-on voltage.
Production of the new diodes was made possible via a newly developed hybrid structure composed of separately embedded structure comprised of a low-voltage unit and a high-current-capable unit, in preparation for high voltage conditions.

Synopsys, Inc. (NASDAQ: SNPS) announced that TetraMAX® ATPG, DesignWare® STAR Hierarchical System and DesignWare STAR Memory System®, key components of Synopsys’ manufacturing test solution, are now certified for the ISO 26262 automotive functional safety standard.
SGS-TÜV Saar GmbH, an independent accredited assessor, formally certified Synopsys’ TetraMAX, STAR Hierarchical System and STAR Memory System following an in-depth Functional Safety Process Audit of the tool and IP development processes.
Certification provides designers with confidence in the use of Synopsys’ test solution for safety-critical automotive applications and accelerates functional safety qualification for automotive ICs, up to the stringent requirements for ASIL D.
Freescale Analog System Basis Chips Receive TÜV SÜD ISO 26262 Functional Safety Assessment to Highest Level
Freescale Semiconductor announces its analog MC33907 and MC33908 system basis chips (SBCs) have received ISO 26262 functional safety assessments up to the ASIL D level from automotive safety assessment organizations.
The assessment was conducted by TÜV SÜD, an independent and renowned functional safety accredited appraiser, which assessed the Freescale products up to the most stringent automotive safety integrity classification.
Panasonic Corporation announced the development of a semiconductor encapsulation material for power devices that boasts heat-resistance performance (glass transition temperature) of 210°C and long-term reliability. It will start shipping samples of the products, CV8540 series, beginning October 2015.
Requirements for vehicles that consume less energy and for smaller sized and lighter weight in-vehicle devices have been increasing. To address these issues, the industry is paying attention to power devices based on silicon carbide (SiC) or gallium nitride (GaN). When used in a vehicle, however, power devices must have superior high-temperature resistance, high-current characteristics, as well as long-term reliability.
Freescale Introduces Highly Integrated, Dedicated Analog ICs for Motorcycle Anti-Lock Braking Systems
October 6, 2015 by John Day
New ICs eliminate the need for a heat sink, paving the way for smaller, lighter and more cost-effective braking control systems for motorcycles and scooters
Freescale Semiconductor (NYSE: FSL) introduced the SB0400 and SB0401 which, according to the company, are the industry’s first highly integrated, dedicated circuits (ICs) specifically engineered for motorcycle and scooter applications.
By incorporating the 7 x 7 millimeter devices into their designs, manufacturers of electronic control units (ECUs) no longer have to rely on much larger ABS ICs developed for automobiles. Instead, they can realize dramatic savings in cost, weight and space with advanced analog parts designed specifically for motorcycles and scooters.
BorgWarner supplies Eco-Launch(TM) stop/start accumulator technology and multi-segment wet friction plates for the new 8-speed rear-wheel drive automatic transmission (8L45) from General Motors.
To enable the transmission’s stop/start functionality, BorgWarner’s Eco-Launch hydraulic accumulator and solenoid valve provide rapid, quiet and smooth engagements during engine restarts.
BorgWarner’s advanced friction plate technology reduces drag and enhances shift feel. Improving fuel economy up to five percent compared with similar 6-speed automatic transmissions, the 8L45 transmission will debut on the 2016 Cadillac CT6 and will also drive the 2016 Cadillac CTS and ATS.
STMicroelectronics Launches Dedicated Telematics Processors to Make Vehicles Safer, Greener and Connected

Renesas Electronics Delivers R-Car W2R 5.9 GHz Band Automotive Wireless Communication SoC for Vehicle-to-Vehicle and Vehicle-to-Infrastructure Communication (V2X)
October 1, 2015 by Jill Beckman
Renesas Electronics Corporation, a supplier of semiconductor solutions, announced the R-Car W2R system-on-a-chip (SoC), the first member of the new Renesas R-Car Family of devices developed specifically for V2X applications. The new automotive wireless communication SoC is designed for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication in the 5.9-gigahertz (GHz) band.
The R-Car W2R uses Renesas’ radio frequency (RF) system design technology. It reduces out-of-band transmit emissions to less than –65 decibel-milliwatts (dBm) (Note 1), achieving the requirements of the European standards organization European Telecommunications Standards Institute (ETSI).
Micronas announced the extension of its direct-angle Hall-effect sensor family HAL 37xy with its dual-die variant HAR 37xy. It integrates two fully automotive-qualified silicon dies in a single SOIC8 package for high-precision direct-angle and linear position measurements for the most demanding automotive and industrial application
HAR 37xy sensors follow the trend of enabling true redundancy within a small package to support safety-critical automotive applications according to ISO 26262 rules.
Toshiba Corporation’s (TOKYO: 6502) Semiconductor & Storage Products Company launched a high-side N-channel power MOSFET gate driver with built-in reverse battery protection functions for use in automotive applications such as idling stop systems. Mass production will start from September 30.
Idling stop systems, which turn off car engines while the car is stopping for traffic lights and traffic jams, are now commonly used in automotive systems as a means to improve fuel efficiency.
The new TPD7104AF gate driver and an N-channel power MOSFET forms a semiconductor relay for each power supply line to control the power supply between the batteries and the starter generator used in idling stop systems.
