I/O Bridging to Multiple Serial Protocols and Advanced Battery Charging Address Developers’ Needs for Lower Power and Flexibility
Microchip Technology Inc., announced the extension of its USB2 Controller Hub (UCH2) portfolio with the new automotive-grade, 4-port USB84604 IC.
Featuring FlexConnect technology and an upstream port that supports both USB2.0 and High Speed Interchip (HSIC) connectivity, the new USB84604 UCH2 is ideal for automotive infotainment system designs, where USB port expansion and connectivity is needed.

Melexis introduced a fully programmable, extremely compact sensor IC capable of accurately measuring changes in magnetic flux density along its X, Y and Z axes.
Based on the company’s proprietary Triaxis® technology, the MLX90393 provides almost unlimited scope with which all manner of human machine interface implementations can be accomplished – from joystick, slide switches, push/pull switches, levelers, linear swipe switches and rotary knobs through to complex 3D position sensing systems. Suitable for micropower applications, the IC draws just 2.5µA of current when idle. It employs a monolithic pixel cell arrangement and has a 16-bit resolution output.

Drivers are taught to assess surrounding traffic before changing lanes by checking their rearview and side mirrors and looking over each shoulder.
But even for those who scrupulously follow this sequence of checks, the vehicle’s blind spot – the area alongside and just behind the vehicle – is a constant source of danger and often the cause of serious accidents.
Typically, two sensor chips are needed today for reliable and precise sensing of the steering torque in an electric power steering system. Thanks to a dual-sensor package innovation of Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY), it will be only one sensor chip in the future.
Infineon today introduced two device families of linear Hall sensors and angle sensors that already use the new dual-sensor package. It supports ASIL D systems and reduces physical space requirements and system cost; for example in steering applications requiring high availability as used in autonomous driving. The dual-sensor package was developed at the Infineon site in Regensburg, Germany.
NI and Alliance Partners Offer Scalable Automotive Functional Test Systems Optimized for Test Throughput
With the growth in electronics in modern-day vehicles continuing to rise and cars becoming increasingly more intelligent, automotive OEMs and suppliers are faced with the challenge of having to innovate quickly and meet short time-to-market demands.
These challenges are made evident on the manufacturing line of the electronic control units (ECUs) when performing functional tests. The continued evolution of ECU functionality combined with the significant volumes of devices being produced is forcing automotive component suppliers to develop a functional testing strategy that will enable them to meet consumer demands most efficiently.

Toshiba Infotainment Companion Chip Supports High-Resolution Multimedia Connectivity, Camera Devices
October 24, 2014 by John Day
Toshiba Corporation introduced the TC358791XBG, an automotive companion chip created to drive high-resolution multimedia (audio, video) and camera connectivity for next-generation infotainment applications in the connected car.
Sample shipments have begun, with mass production scheduled to start in March, 2015.
The TC358791XBG can help reduce both time to market and overall system bill-of-materials costs for automotive infotainment systems.
The new chip supports the latest automotive Gigabit Ethernet AVB standard for applications such as front, rear and surround-view cameras, digital audio, and transferring high-resolution video content to head-unit and rear-seat entertainment systems.
Pre-Collision Assist with Pedestrian Detection uses radar and camera technology to scan the roadway ahead and, if a collision risk with a vehicle or pedestrian is detected, provides a warning to the driver. If the driver does not respond in time, the system can automatically apply up to full braking force to help reduce the severity of or even eliminate some frontal collisions.
New TI SoC, TDA3x, Supports Front, Rear and Surround View ADAS Applications for Entry- to Mid-Level Cars
At the SAE Convergence conference in Detroit, Texas Instruments (TI) introduced the newest member of its automotive system-on-chip (SoC) family, the TDA3x.
It’s intended to help automakers develop ADAS (Advanced Driver Assistance Systems) applications that meet or exceed NCAP (New Car Assessment Program) requirements, reduce collisions, and enable a more autonomous driving experience in entry- to mid-level vehicles.

Electrical Systems (ES) engineers at the Toyota Technical Center in Saline, Michigan, spent months engaged in customer research in the course of designing the 2015 Toyota Avalon premium midsize sedan that launched this week.
The research included clinics, focus groups, surveys, and visits to dealers.
“A tremendous effort goes into designing a car that meets design goals,” says Avalon chief engineer Randy Stephens. “The (Avalon) powertrain was the same as that in the previous generation, and we had a really competitive powertrain, so what we wanted to do was change everything around it to have this vehicle match our vision.

Compared with conventional solutions, the warning light built into the door latch is visible to road users through the entire opening radius.
The LED latch’s intelligent system architecture saves on packaging space and assembly time and the weight of the side door is reduced. The energy-saving LED lamp also makes an added contribution to improved economy and sustainability.
Application options for the LED latch include a choice of color and brightness, flashing LEDs, child locks and emergency locking.
