New High Accuracy Current Sense Amps Compatible with Both Negative and High Voltages

　　ROHM has developed a new lineup of high accuracy current sense amps – the BD1423xFVJ-C and the BD1422xG-C. They are qualified under the AEC-Q100 automotive reliability standard. The BD1423xFVJ-C series, offered in the TSSOP-B8J package, supports input voltages up to +80V, making it ideal for high-voltage environments such as 48V DC-DC converters, redundant power supplies, auxiliary batteries, and electric compressors. The series includes three models with different gain settings: BD14230FVJ-C, BD14231FVJ-C and BD14232FVJ-C.　　For lower voltage use cases, the BD1422xG-C, available in the compact SSOP6 package, supports input voltages up to +40V. This makes them suitable for automotive applications requiring space-saving designs, such as current monitoring and protection (overcurrent) in 5V/12V power supply networks used in body and drivetrain domains. Like its high-voltage counterpart, this series also consists of three different gain options: BD14220G-C, BD14221G-C and BD14222G-C.　　In recent years, alongside conventional 5V/12V power supplies, the automotive market has seen a growing adoption of 48V systems fueled by the rising popularity of electric vehicles. Furthermore, as vehicle functionality becomes more advanced, the need for precise monitoring and control across a wide range of applications continues to increase, placing a greater importance on high-accuracy current sensing.　　A current sense amp indirectly measures the current flowing through a circuit by amplifying the miniscule voltage drop across a shunt resistor. The amplified signal is then sent to an ADC or comparator for system control and monitoring. ROHM’s automotive-grade current sense amps meet market demands by leveraging proven analog expertise. This enables high-accuracy current sensing with compatibility for both negative and high voltage environments, contributing to improved safety and reliability in automotive applications, particularly electric vehicles.　　These new products achieve greater space efficiency by integrating most of current sensing circuitry, typically comprised of an operational amplifier and discrete components, int o a single package. As a result, current detection is possible by simply connecting a shunt resistor. The devices also feature a two-stage amplifier configuration, consisting of a chopper amplifier at the input and an auto-zero amplifier at the output. Internal resistor matching for gain setting ensures stable, accurate current sensing (±1%) while minimizing the effects of temperature variations.　　Furthermore, current detection accuracy is maintained even when an external RC filter circuit added for noise suppression, significantly reducing design complexity and development time. Additional features include -14V negative voltage tolerance that supports back electromotive force, reverse connection, and negative voltage input.　　Going forward, ROHM will continue to deliver optimal solutions that contribute to higher precision and enhanced reliability in automotive equipment.　　Application Examples　　• BD1423xFVJ-C (for 48V systems): Redundant power supplies, auxiliary batteries, DC-DC converters, and electric compressors, and the like　　• BD1422xG-C (for 5V/12V systems): Body DCUs (Domain Control Units) / ECUs (Electronic Control Units), etc.　　Terminology　　AEC-Q100 Automotive Reliability Standard　　AEC stands for Automotive Electronics Council, a reliability standard for automotive electronic components established by major automotive manufacturers and US electronic component makers. Q100 is a standard that specifically applies to integrated circuits (ICs).　　Shunt Resistor　　A resistor connected in series in the current path to detect the current in the circuit by measuring the potential difference across it.　　Chopper Amp　　An amp circuit designed to minimize signal offset and noise, primarily used for accurately amplifying low-frequency and weak DC signals.　　Auto-Zero Amp　　An amp that automatically compensates for offset voltage (unwanted noise and errors) by continuously sampling and correcting it during operation. This ensures high signal accuracy, making it ideal for applications that demand ultra-precise measurement and signal processing.

Nidec Instruments Develops Vacuum-resistant Liquid Crystal Substrate Transfer Robots

　　Nidec Instruments Corporation (“Nidec Instruments” or the “Company”), a wholly owned subsidiary of Nidec Corporation, today announced the development of liquid crystal substrate transfer robots that can move their joints in a vacuum environment as freely as in the air.　　In a process to manufacture liquid crystal, organic electroluminescent (EL), and other displays, mother glass substrates are constantly required to be made larger, and their processing speed faster, as their production cost must be reduced and screen sizes must be made larger at the same time. In recent years, display manufacturers are required to handle large, 3m x 3m products because the larger glasses robots can transfer, the better transfer efficiency they can achieve.　　As mother glass substrates’ thin-film and vapor deposition processes require an extremely clean vacuum environment, transfer robots used in such processes must be vacuum-resistant as well.　　As the company with the largest global market share for transfer robots used in organic EL substrates’ vapor deposition process, Nidec Instruments utilized its knowhow in these latest products as well. Robots that operate in vacuum have joints with seals to keep air and dust inside their arms and other parts. Though such sealing mechanisms restrain the movements of transfer robots’ joints, the Company’s latest products adopt magnetic seals integrated with reducers to minimize the seals’ use, and thus secure the same level of freedom as in the air. To meet its customers’ needs, Nidec Instruments has added two new modes with different arm shapes, i.e., a boomerang type and a scalar type, to its product lineup, while suppressing cost by using common units for them.　　As a member of the world’s leading comprehensive motor manufacturer, Nidec Instruments stays committed to offering revolutionary solutions that contribute to creating a comfortable society.

IDC Expects Asia/Pacific excluding Japan Spending on Robotics to Reach US$129.4B in 2022

　　The latest IDC Worldwide Semiannual Robotics and Drones Spending Guide forecasts Asia Pacific excluding Japan (APEJ) spending on robotics (including drones) and associated services to reach USD 129.4 billion by 2022, essentially three times the spending in 2018, with a five-year CAGR of 25.2% during 2017-2022. APEJ tops with the largest market share for robotics applications followed by the United States and Japan. Both are expected to record for more than 61.6% of the world’s entire robotics market in 2022.　　"To survive the escalating competition, APEJ manufacturing organizations surveyed by IDC in 2018 are putting robotics as their top priority for technology investment," said Dr. Jing Bing Zhang, Research Director for Worldwide Robotics at IDC. “While the uncertainty of the trade war between the United States and China is likely to dampen the market growth in the near term, we expect the growth trend to pick up from 2020 onward.”　　Discrete and process manufacturing are the dominant industries in robotics (including drones) spending, which turns over 58.1% of the overall spend in APEJ in 2019. Largely, welding and assembling use cases in discrete manufacturing, whilst pick and pack, and bottling use cases in process manufacturing are driving the robotics spend in 2019. However, customer deliveries, vegetable seeding and planting are the drone use cases which we expect to grow at fast pace with a five-year CAGR 126.4% and CAGR 112.1% respectively over the forecast period (2017-22).　　“There has been an intensive wave of industrial automation for which robotics and drones provide a major base; hence attracting investments with each passing year. Under Robotics, despite Manufacturing being a dominant industry in this area, investments will continue to increase in resource industry, retail, construction, among others,“ said Swati Chaturvedi, Senior Market Analyst at IDC.　　“On the other hand, drones, which are majorly a consumer-oriented technology, are gaining momentum in its industrial usage by enterprises and governments alike for tasks as mundane as filmmaking and inspection or as complex as agricultural uses, mining operations assistance, and insurance assessment.”　　From a technology perspective, hardware purchases related spending on robotics systems (including drones) in APEJ, which includes industrial, service and consumer robots and after-market hardware, is forecast to grow to $81.0 billion in 2022.　　China accounts largest market share in the Asia Pacific robotics (including drones) market. Its spending on robotics is expected to reach $80.5 billion, representing 62.2% of APEJ region's total spending in 2022.

Industrial Bots to Get Smarter, More Talented

　　Robots that vacuum our floors, talk to us in malls, or disable IEDs may be more interesting to think about, but the industrial robots that put together cars and do pick-and-place on assembly lines are worth far more in total dollar value.　　They're also making more and more of the industrial, commercial and consumer goods we use. Some recent research reports on trends in industrial robots say demand is growing especially in Asia and especially in electronics manufacturing, and technology will give these robots a lot more abilities in the next few years.　　The key study is from the International Federation of Robotics (IFR), based in Germany. According to the IFR's World Robotics: Industrial Robots 2017 report, global unit sales of industrial robots increased at an average of 12 percent per year between 2011 and 2016, with a 16 percent increase in 2016 over 2015.　　Asia is still the fastest-growing market in the world for these bots. Unit sales there rose by 19 percent in 2016, compared to 12 percent in Europe and 8 percent in the Americas. The sales value of the global market for industrial robots was $13.1 billion in 2016.　　China has maintained and expanded its leadership as the biggest industrial robot market for several years, growing at an average of 31 percent per year between 2011 and 2016.　　Although the two largest buyers of industrial robots are China and South Korea, China and the U.S. had the two biggest gains in 2016 unit sales at 27 percent and 14 percent, respectively. Sales to Japan rose 10 percent and to South Korea by 8 percent, while sales to Germany, the fifth largest market, were flat. These five countries constituted 74 percent of the total sales volume in 2016 for industrial robots.　　Automotive manufacturing (35 percent) and electrical/electronics manufacturing (31 percent) continue to be the two biggest users of industrial robots worldwide. Compared to automotive's slow growth of only 6 percent in 2016, electrical/electronics usage has been rising rapidly during the last couple of years: unit sales were up 41 percent since 2015. In most Asian markets this industry sector is now the biggest robot user.　　The IFR report points out that looking only at the total number of units sold in a given market can be misleading if the different sizes of manufacturing industries in different countries aren't taken into account. To give a more accurate picture, analysts calculated industrial robot density per 10,000 employees in manufacturing for 2016. The global average density was 74 industrial robots installed per 10,000 employees.　　By world regions, industrial robot density is highest in Europe at 99, followed by 84 in the Americas, and 63 in Asia. By country, Singapore's overall robot density is 488, followed by Germany at 309, Japan at 303, 189 in the U.S., and 68 in China.　　Although China's figure may seem low considering its dominance in total volumes, that's a big increase since the figure of 25 in 2013. But it also points to how far China must go to achieve its goal of achieving advanced manufacturing, including Industry 4.0-style automation, as part of its Made in China 2025 initiative.　　But the highest level in the world of industrial robot density is South Korea's 631. The report says this is caused by heavy increases in industrial robot installations for both electrical/electronics manufacturing, due to this country's market leadership in LCD, memory chip and automotive manufacturing. The automotive industry itself is so highly automated that in South Korea its robot density is 2,145. In the U.S. and Japan it's 1,261 and 1,240, respectively.　　Between 2018 and 2020, the number of worldwide industrial robots in operation is expected to grow at an average of 15 percent per year. In the U.S., the main drivers for continued growth since 2010 have been the ongoing automation of production to strengthen American industrial competitiveness in overseas markets, with investments made both to keep manufacturing onshore and to bring it back from overseas locations where it had previously been relocated. This trend has been especially strong in the automotive sector. Most industrial robots used in the U.S. are imported from Japan, Korea, and Europe.　　According to IDC robotics analysts, several technologies will bring new abilities to industrial robots, and other types, in the next few years. By 2020, 45 percent of newly installed industrial robots will have at least one intelligent feature, such as predictive analytics, health condition awareness, self-diagnosis, peer-learning, or autonomous cognition. This is one of IDC's "Top 10 Worldwide Robotics Predictions", also given in a presentation last November 2017 by Jing Bing Zhang, IDC's research director for worldwide robotics, and John Santagate, research director for service robotics.　　"These are not so much new technologies as they are additional technologies — machine learning, intelligence, industrial internet of things connectivity, and predictive maintenance because of that connectivity — being layered onto existing robotics technologies," said Santagate. Another prediction is that by 2021, intelligent robotics agents will supervise and coordinate industrial robots, boosting their overall efficiency by 30 percent.　　Another report, made last year by Allied Market Research, measures robot growth primarily in dollar value, not units, and slices up industries somewhat differently from the IFR. The firm's Industrial Robotics Market Report forecasts that the global industrial robotics market will grow from a value of $27 million in 2012 to $41 billion by 2020, at a compound annual growth rate (CAGR) of 5.4 percent between 2013 and 2020.　　While automotive manufacturing is the largest user of industrial robots, analysts expect its growth to slow to a CAGR of only 4.9 percent during the period, caused by slowdown in the automotive industry during the past few years. Use of industrial robots in the food & beverages sector is expected to grow faster, at a CAGR of 6.9 percent between 2013 and 2020.

IDC TechScape Assesses Technologies Related to Adoption of Service Robotics

　　Worldwide Service Robotics, 2018 (IDC #US42954518), which provides a systematic assessment of technologies related to the adoption of service robotics. Robotic technology has evolved from a technology used predominantly within industrial manufacturing to a technology that now has applicability across a much wider set of industries and use cases. When thinking about this evolution, IDC considers the role of other technology areas that have helped drive innovation in the field of robotics. This new report is intended to help senior executives assess their organization's technology landscape to determine whether their efforts are aligned with analyst's assessment of the industry's overall technology adoption progress.　　Across industries, companies are looking at the viability of robots as a mechanism to support process improvement, drive productivity and efficiency gains, support cost management, and offset labor related challenges that appear to be hindering business process effectiveness in some industries. While some robotic applications are designed to solve a very specific business problem, other robotic technology has been built with the flexibility to be applied across different business processes and industries.　　The IDC TechScape provides a visual representation of the process of technology adoption, dividing technologies into three major categories (Transformational, Incremental, and Opportunistic) based on their impact on the organization and assessing the technologies relative to adoption levels within their respective categories. Technologies evaluated in the new report include 3D printing, artificial intelligence, autonomous guided vehicles, exoskeletons, and virtual reality.　　IDC expects that executives responsible for information technology strategies will use the IDC TechScape model to:　　Assess the progress of their own technology adoption efforts in comparison with the industry overall.　　Identify new technologies that should be added for consideration in their technology road map.　　Add new insights to increase the robustness of their own technology decision frameworks.　　"The use of robotics in nontraditional applications is growing as technology innovators continue to push the envelope on what a robot is capable of doing," said John Santagate, research director, Service Robots at IDC. "Service robots have not evolved on their own; the current state of service robots has been enabled by the maturity of several other related technology areas that have helped to deliver robots with greater and more versatile skill sets than previous generations of robotics."
