International Rectifier (IR) (NYSE: IRF) introduced the automotive-qualified AUIRB24427S high current dual low-side driver IC for Switched Mode Power Supply (SMPS) applications used in Hybrid Electrical Vehicles (HEV), Electric Vehicles (EV), and high power industrial converters.
The AUIRB24427S features very high output current in excess of 6A per channel across the full temperature range and is designed to drive large IGBT and MOSFET gates in modules or discrete packages.
Due to the device’s extremely low output impedance in turn-on and turn-off mode, power losses are also very low, allowing operation in harsh and high temperature environments such as HEV power supply stages as a primary or secondary side driver.
Single-Chip Device Packs Company’s Image Recognition Technology and Other Functions for High-Performance, Low Power, and Improved Safety
Renesas Electronics Corporation (TSE: 6723) announced the availability of its R-Car V2H, the company’s newest system-on-a-chip (SoC) implementing state-of-the-art image recognition technology to support high-resolution surround viewing in advanced driver assistance systems (ADAS).
This is the first R-Car ADAS device from Renesas and includes additional functionality for higher performance, lower power, and improved safety in traditional and emerging self-driving vehicles.
Webasto-Edscha, Webasto’s convertible business unit, is for the first time the exclusive manufacturer of the soft top for the award-winning seventh generation Chevrolet Corvette Stingray Convertible. The convertible roof has a number of lightweight components, providing even more headroom and features an improved design.
A German-American project team of engineers from Webasto’s Hengersberg site in Lower Bavaria and its American plant in Plymouth, Mich., developed the convertible top for the Corvette. The series production of the roof system takes place in Plymouth, with the soft top and inner lining delivered from the textile competence center in Puebla, Mexico.
Easing Automakers’ Concerns
The motor marks an important breakthrough since it will ease concerns among automakers about their reliance on uncertain rare earth supplies. Rare earth elements are usually used in materials for automotive motors, but they are difficult to source and are subject to sharp price increases when supplies dwindle.
There are only small and concentrated reserves worldwide of the rare earth minerals, which are often used to provide magnetic properties for automotive motors.
Visteon Introduces Industry-First Dual Compatible In-Vehicle Wireless Charging System for General Motors
Visteon Corporation (NYSE: VC) is debuting its first-to-market wireless charging system with General Motors. The solution uses inductive coupling technology to support both wireless charging standards – Power Matters Alliance (PMA)/Powermat® and Wireless Power Consortium (WPC)/Qi.
Cadillac is featuring it on the 2015 ATS, and will add it to the CTS sports sedan this fall and to the Escalade SUV at the end of 2014.
Wireless charging gives vehicle occupants a convenient way to recharge their mobile device and eliminates the need for power cords. It addresses what a recent study conducted by the WPC found to be the biggest complaint of smartphone users: battery life.
Low battery warnings are never welcome but seem ever present with the increasing reliance on portable electronics in our personal and professional lives.
Combining the automotive grade NFC (Near Field Communication) transceiver of Melexis with Freescale Semiconductor’s wireless charging technology enables a ready to use reference design solution that could free us from the dreaded low battery warning.
Freescale Introduces Programmable Wireless Charging Solutions for Automotive and Consumer Applications
The new Wireless Power Consortium (WPC) Qi-certified transmit controller ICs and reference designs are fully qualified and available now.
In-Vehicle Wireless Charging
As feature-rich, power-hungry mobile devices rapidly proliferate, the need to charge anywhere grows imperative.
The U.S. Census Bureau estimates the average American’s daily work commute time to be about 50 minutes, and more consumers are bringing their mobile lives into the car expecting the same options as the home for charging and connectivity – thereby fueling demand for in-vehicle wireless charging.
Renesas Electronics Corporation (TSE: 6723) announced the RH850/C1x Series of 32-bit microcontrollers (MCUs), designed for motor control in hybrid electric vehicles (HEVs) and electric vehicles (EVs).
Based on Renesas Electronics’ 40-nanometer (nm) process, the RH850/C1x Series features the RH850/C1H and RH850/C1M MCUs, which enable embedded designers to enhance efficiency, reduce system costs, and achieve higher safety levels for HEV/EV motor control systems.
24V Triple Output Synchronous Step-Down Controller Features –55°C to 150°C Junction Temperature Range
Linear Technology Corporation announces the H- and MP-grade versions of the LTC3853, a triple output synchronous step-down switching regulator controller.
This device operates over a 4.5V to 24V input voltage range, can produce output currents up to 20A per phase with output voltages ranging from 0.8V to 13.5V at up to 95% efficiency. These H- and MP-grade versions are guaranteed over operating junction temperatures from –40°C to 150°C and –55°C to 150°C, respectively.
The LTC3853 has powerful 1.1 Ohm on-chip MOSFET gate drivers. A constant-frequency current mode architecture allows a selectable fixed or synchronized frequency from 250kHz to 750kHz.

A sizable percentage of garbage trucks (solid waste collection vehicles) in California no longer meet California Air Resources Board (ARB) emission standards and must be replaced. New trucks cost in the vicinity of $500,000.
A San Jose company, Wrightspeed, offers a solution that is attracting the attention of solid waste fleet owners. It has developed a plug-in electric powertrain that can be retrofitted on the trucks in question, allowing them to surpass ARB’s emissions standards by 1,000 percent.
