Magna International is supplying two industry-first systems on the BMW i8 plug-in electric sports car: outside mirrors with hidden turn signals and SmartLatch(TM), an electronic side-door latch system.
The unique design of the outside mirrors includes a hidden turn signal that is fully integrated so that the mirror housing and turn-signal lens are one and the same. The signal is invisible when not in operation, which allows for styling improvements and improved aerodynamics with no additional gaps or incremental wind noise.
The BMW i3 model in volume production today includes an AS8510 in the battery sensor. The battery management system (BMS) monitors battery voltage and battery current of the 400V li-ion battery powering the cars’ electric motors, and ensures the functional safety of the vehicle’s battery systems.
Freescale Battery Cell Controller Balances Measurement Accuracy, Scalability and High Speed Communications
Electric and Hybrid Vehicle Technology Expo –Freescale Semiconductor (NYSE: FSL) announced a highly integrated 14-cell lithium-ion battery cell controller for industrial and automotive applications, designed to cost effectively meet the stringent requirements for ASIL-C functional safety.
With fourteen cell balancing transistors, a current sensor with ±0.5% accuracy from milliamps to kiloamps, and 2 Mbps communication transceiver interface integrated into a single 64-pin QFP package, Freescale’s MC33771 battery cell controller and companion MC33664 isolated communications interface deliver robust, reliable performance for 48 V battery systems, enabling economical scalability beyond 1000 volts.
The STH315N10F7-2, STH315N10F7-6, and STP315N10F7 feature an optimized body-drain diode performance that minimizes voltage spikes and switching noise over the operating voltage range, allowing more robust, reliable, and power-efficient designs.
STripFET™ F7 devices exploit an enhanced trench-gate structure that lowers device on-state resistance while simultaneously reducing internal capacitances and gate charge to deliver faster and more power-efficient switching.
The three new devices bring these benefits to the automotive market, offering the industry’s lowest RDS(on) x Area and turn-off energy (Eoff) parameters available in the automotive market.

New family of 36-V and 60-V converters for energy-efficient, EMI-compliant systems
Texas Instruments (TI) introduced seven SIMPLE SWITCHER regulators that simplify wide V(IN) synchronous power supply design and help engineers create energy-efficient, electromagnetic interference (EMI) compliant products.
The easy-to-use LM43600/1/2/3 and LM46000/1/2 DC/DC converters feature an input voltage range of up to 60 V for high reliability in rugged systems, and 27 micro amps of standby current that minimizes power consumption at light load.
Vishay Intertechnology Automotive-Grade PIN Photodiodes Deliver High Reverse Light Current to 9.5 µA
September 11, 2014 by John Day
Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with the introduction of two new automotive-grade high-speed silicon PIN photodiodes in clear- and black-epoxy 1206 surface-mount packages measuring 4 mm by 2 mm by 1.05 mm.
Offering a sensitive area of 0.85 mm², the Vishay Semiconductors VEMD6010X01 and VEMD6110X01 provide a high reverse light current of 9.5 µA — three times that of previously released devices — and a very low dark current of 1 nA for automotive and industrial applications.
The Hyundai Assurance Car Care in-vehicle app is now available for download into the multimedia system of 2015 Sonatas equipped with navigation.
Sonata owners can use the in-vehicle app as another convenient option for accessing car care services and vehicle information.
The Hyundai Assurance Car Care in-vehicle app has similar features to the Hyundai Assurance Car Care mobile app but takes advantage of Sonata’s eight-inch multimedia touchscreen.
Customers can use the in-vehicle Care app as a convenient option for scheduling an oil change at their favorite dealership, access Hyundai’s first on-screen interactive owner’s manual, providing a convenient and simpler way for owners to become familiar with the full capabilities of their vehicle.
Cohda Wireless launched the MK5, its fifth-generation ‘talking vehicle’ product. The MK5 provides advance warning of potential dangers to vehicle safety by wirelessly gathering data from similarly equipped vehicles and infrastructure.
The MK5 addresses both Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) implementations, collectively referred to as V2X. Offering best in class performance, the MK5 is suitable for use in trials, automotive production, aftermarket products and roadside infrastructure. V2X technology is expected in production vehicles from 2016.
Cohda Wireless CEO Paul Gray said the MK5 was available as an onboard, roadside or radio module. “The MK5 is Cohda’s smallest product to date, measuring just 90mm x 130mm for the onboard unit and 30mm x 40mm for the radio module,” he said.
To meet the growing demand for AEC-Q200-qualified parts, Vishay Intertechnology, Inc. (NYSE: VSH) announced that its MC AT professional series of automotive thin film chip resistors is now AEC-Q200-qualified over its entire resistance range from 1 Ω to 1 MΩ.
Designed to deliver stability under harsh environmental conditions in automotive and industrial applications, the Vishay Beyschlag devices offer high-temperature performance to +175 °C for 1,000 hours.
