Infineon Tech 48V

Infineon Technologies AG expects significant growth in automotive 48 V systems in the coming years and is expanding its portfolio of suitable power devices. The chip manufacturer is launching new packages for its 80 V and 100 V MOSFETs with OptiMOS™ 5 technology to meet the different requirements of different 48 V applications. In view of the expected increase in demand, Infineon has set up a new manufacturing process to now produce the chips on its line for 300-millimeter thin-wafers in Dresden, Germany.

“In this decade, we will reach the point where the majority of all newly produced cars worldwide have a partially or fully electric powertrain,” said Stephan Zizala, Vice President and General Manager Automotive High Power at Infineon. “According to market research, production of models with 48 V power supply and a mild hybrid drive is likely to increase more than tenfold between 2020 and 2030. In addition to our portfolio for high-voltage systems in battery-electric drives as well as full and plug-in hybrids, we therefore also strengthen our offering for 48 V systems with new devices and expanded supply capacities.”

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) extends its embedded SIM (eSIM) portfolio with the new OPTIGA™ Connect eSIM solution for mobile consumer devices. This solution fully supports all GSMA standards from 3G to 5G and securely authenticates the device to the subscribed carrier network of choice. It is the perfect match for smartphones, tablets and wearables like smart watches or fitness trackers thanks to its small footprint. Combining hardware and software in an easy to integrate system, Infineon helps manufacturers to develop product designs efficiently by reducing their eSIM integration efforts and time to market.

Based on Infineon’s proven SLC37 security chip, the new OPTIGA Connect solution meets the GSMA’s security requirements and is tested according to Common Criteria CC EAL4+ high. The chip at its core provides a robust and trustworthy vault which is necessary to secure sensitive keys and data against fraudulent use.

Furthermore, the solution fully complies with the latest 5G specifications from the GSMA (SIMAlliance Profile Interoperability 2.3 Spec) and the 3GPP. It supports the profiles of major mobile network providers with Remote SIM Provisioning capabilities and offers up to 1.2 MB of free user memory for network operator profiles, data and additional applications. The ultra-small package size of only 2.9 mm x 2.5 mm x 0.4 mm allows completely new designs, especially for devices where printed circuit board space is of greatest value.

According to the global tech market advisory firm ABI Research, global shipments of eSIM enabled smartphones is expected to propel to over 225 million in 2020. Based on a continuation of eSIM support from leading handset manufacturers and eSIM expansion into other device ranges, ABI expects a minimum of 500 million eSIM capable smartphones to ship globally in 2024.

Portfolio expansion at both ends of the power spectrum

Infineon offers a variety of 80 V and 100 V MOSFETs in OptiMOS 5 technology with very low, scalable on-state resistances down to 1.2 mΩ. For the core applications of a mild hybrid, for example starter generators, battery switches and DC-DC converters, where high power densities are required, Infineon is expanding its TOLx package family. This is based on the established TOLL (TO-Leadless, 10 mm x 12 mm) product for standard copper substrate PCBs and currents up to 300 A.

In addition, the family comprises the TOLG (TO Leads Gullwing Design) package with identical footprint for Insulated Metal Substrates (IMS) with aluminum core. Since the thermal expansion coefficients of copper and aluminium differ, the use of IMS boards under high thermo-mechanical stress leads to increased stress on the soldered connections between package and PCB. In order to mitigate this stress, the TOLG package is equipped with gullwing leads.

New package for top-side cooling

In the next step, Infineon will expand the TOLx family with a third member that is unique among the competition: the TOLT (TO Leads Top-Side Cooling) package. It enables heat dissipation through top-side cooling via the top of the package instead of via the PCB. This allows an increase in power of more than 20 percent and reduces the necessary cooling effort on the board. The start of volume production of TOLT products is planned for 2021.

Next to the TOLx family, Infineon also expands the package portfolio addressing less power-hungry auxiliaries such as fans and pumps that are also increasingly being transferred to the 48 V supply. Completely new are versions in the small S3O8 package (3.3 mm x 3.3 mm) for lower currents up to 40 A. They complement products with the slightly larger SSO8 package (5 mm x 6 mm) for currents up to 100 A that were added to the portfolio recently.

Mild hybrid drives based on a 48 V supply are a fast and cost-effective way for car manufacturers to achieve lower CO 2 fleet emissions . Among other things, they allow a higher recuperation energy compared to a 12 V system and use the energy gained for electrical support of the combustion engine. In addition, a 48 V supply offers performance and efficiency advantages for safety and comfort functions with high current loads, such as stability control or air-conditioning compressors. Depending on the configuration of the drive system and the number of auxiliary units, a mild hybrid can reduce CO 2 emissions by up to 15 percent compared to a pure combustion engine.]]]

Toyota Develops Electrosatic Airless Sprayed Paint

Toyota Motor Corporation (Toyota) has developed a new type of paint atomizer (airless paint atomizer) that uses static electricity instead of air, to replace the conventional air paint atomizers used in the vehicle body painting process. The newly developed airless painter, the first of its kind in the world*, achieves over 95 percent coating efficiency (the amount of paint sprayed versus the amount that actually adheres onto the vehicle body), the highest in the world*, from conventional efficiency of approximately 60 to 70 percent.

By deploying the airless paint atomizer in Toyota Group’s painting process, it is expected that the Group can reduce its CO2 emissions by about 7 percent. In addition, the collection device situated at the bottom of the paint booth (the area where paint is sprayed) can be made more compact. Therefore, it is able to make painting production lines more compact for the future.

Toyota is advancing initiatives to achieve its Plant Zero CO2 Emissions Challenge, one of the targets included in the Toyota Environmental Challenge 2050 announced in 2015. As part of this effort, it developed the airless paint atomizer and deployed it at both Takaoka and Tsutsumi Plants. Gradual deployment at other plants is planned as well as consideration of deployment among other Toyota Group companies and licensing the technology to other companies.

Conventional air paint atomizer sprayed paint primarily using aerodynamic force, then paint the vehicle body with the atomized particles using an air paint atomizer. For this reason, paint particles are scattered by the air ricocheting off the vehicle body, resulting in a coating efficiency of approximately 60 to 70 percent. By comparison, the new airless paint atomizer uses electricity to sprayed the paint (electrostatic atomization), and the statically charged particles coat in such a way that they gravitate toward the vehicle body (electrostatic painting). Electrostatic atomization and electrostatic painting technologies greatly reduce the number of atomized particles that scatter, thereby achieving a higher coating efficiency.

New technologies that achieve high coating efficiency

  1. The tip of the airless paint atomizer features a rotating cylindrical head that optimize the amount of paint sprayed

Electrostatic atomization technology is used in beauty treatment devices and other instruments that spray fine amounts of liquid; here, we applied it to vehicle body painting. Specifically, the tip of the paint sprayer is cylindrical. Approximately 600 special grooves are inserted into the tip, which is rotated to create a centrifugal force, inducing the paint to flow into the grooves and atomize through static electricity. In this way, we developed the world’s first technology that paints vehicle bodies with atomized paint particles using static electricity.

  1. Highly accurate current control that makes close-range painting possible

The unevenness of the vehicle body causes the distance between the cylindrical head and the vehicle body to fluctuate, making the electrical current unstable. However, the airless paint atomizer constantly monitors the variations in current and automatically controls the voltage, maintaining a distance of approximately 10 centimeters between the cylindrical head and the vehicle body. Hence, electrostatic atomization and electrostatic painting under a fixed current is rendered possible, in turn preventing variation in the size of the paint particles―the result is high-quality painting.

OmniVision  Second Gen NIR Imaging

OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, announced Nyxel® 2—the second generation of its revolutionary near-infrared (NIR) technology for image sensors that operate in low to no ambient light conditions. Despite launching the first generation more than two years ago, competing mass-produced CMOS image sensors are still failing to achieve comparable NIR performance. Meanwhile, OmniVision’s R&D team has continued to refine its novel silicon semiconductor architectures and processes to achieve new records in quantum efficiency (QE), with Nyxel 2 now providing a 25% improvement in the invisible 940nm NIR light spectrum and a 17% bump at the barely visible 850nm NIR wavelength.

These sensitivity improvements enable image sensors to see even better and farther under the same amount of light, further extending the image detection range. Nyxel 2-based camera systems also require fewer LED lights, thus reducing overall power consumption and extending battery life. These added benefits make Nyxel 2 an ideal technology for surveillance systems, automotive in-cabin driving monitoring systems and the burgeoning under-display sensors in mobile devices.

With these refinements, OmniVision’s Nyxel 2 can now achieve 50% QE at 940nm—a 25% improvement over the first generation, as measured using data from a 2.9 micron pixel. At the 850nm NIR wavelength, Nyxel 2 can provide 70% QE, which is not only a 17% improvement over the first generation, but it is now on par with the QE levels of top RGB sensors that operate with visible light. The results of these Nyxel 2 technology improvements are even higher and still unrivaled image quality, greater image detection range, and further reduction in light source requirements for even lower power consumption and extended battery life.
