A few days ago, EEWORLD interviewed Li Xiaozheng, Automotive E-Commerce Manager of ADI Greater China for automotive electronics in terms of active safety and electric vehicles. He introduced in detail the new products introduced by ADI for popular technologies and how ADI ensures the quality of automotive electronics. For the delivery cycle, the following is an interview record.
EEWORLD: How does ADI understand the role of semiconductor manufacturers in the safe driving of automotive electronics?
Li Zhenzheng: In 2000, the United States Congress passed the Transportation Recall Enhancement Accountability and Documentation (TREAD), forcing automakers to adopt new safety technologies and reminding the government of possible dangers.
In China, after several years of rapid development, consumers have gradually shifted their demands for basic vehicle functions to higher levels such as security. More and more automakers are turning to electronic and high-tech solutions to solve safety problems, and high demand has also made the car safety system more and more intelligent. For semiconductor manufacturers, we must first provide a reliable chip, so that the module supplier's raw materials are guaranteed, and the quality of the produced modules is stable.
ABI's report shows that the average number of automotive semiconductor components is growing exponentially, and a series of safe, advanced engine and chassis control electronics as well as automotive safety products will be adopted in new models in the coming years. All of these will increase the demand for semiconductor manufacturers to control the defect rate, improve stability, and so on.
EEWORLD: At present, active safety is getting more and more attention. In the passive safety, especially in the airbag, ADI is how to play a role in active safety.
Li: Today, more and more attention is paid to the active safety technology of automotive electronics. Nowadays, more advanced research and development are advanced driver assistance systems (ADAS). The core of this system is to detect the driving status of the car and the surrounding environmental information through video or radar technology, processed by DSP, and then take corresponding measures. There are only warning drivers, while others take some intervention measures such as braking. Since the core of active safety is the acquisition and processing of signals, this has high requirements for semiconductor manufacturers in terms of analog technology, high-frequency technology, and digital processing.
In active safety, such as advanced driver assistance systems, more and more attention has been paid to consumers. We provide intelligent assisted driving based on vision and radar technology to realize lane departure warning, obstacle detection, traffic signal recognition, etc. In this system we have our DSP (BF561), video codec, ADC/ Chips such as DAC/RF are widely used. As the design of automobiles continues to be complex and the requirements for safety systems continue to increase, the demand for the development of assistive driving systems by customers is not just at the chip technology level, and the resources and support at the application and system software level are also indispensable.
For this application, the dependence on software is relatively high. Most Chinese customers have relatively weak R&D capabilities. ADI has a dedicated software team in India to develop the underlying algorithms. Over the years, it has developed a large number of outstanding products in the automotive industry. Tripartite partners can work with ADI to provide customers with complete system support and services.
ADI has introduced a highly integrated AD8283 automotive radar AFE (Analog Front End) IC this year that includes receive path signal conditioning and data acquisition circuitry that enables end systems to implement adaptive cruise control, blind spot detection, and other radar-based detection and prevention applications. The six-channel AD8283 is AEC-Q100 certified and can operate in the -40C to 105C automotive application temperature range. The new device allows radar systems to receive a greater number of transmitted signals and decode them for target recognition and classification. This makes the positioning time more abundant, thereby improving the radar's ability to resolve the approximate size of the target.
EEWORLD: Automotive Electronics is similar to industrial control electronics and needs special emphasis on product yields, lead times, and reliability. How do ADI guarantee these points?
Li: As the popularity of automobiles gets higher and higher, consumers' safety awareness will become stronger. For semiconductor manufacturers, we must first provide reliable chips, so that the raw materials of module suppliers can be guaranteed and produced. The quality of the module is stable. When it comes to automotive-grade chips, many people may be limited to the temperature parameter. In fact, this is only a characteristic of the chip. In order to ensure that the chip can reach the automotive level, first of all, it has a strict process in the design phase. If you want to strictly follow the DFMEA, AEC-Q003 process, and second, the Fab process, probe testing and other applications of the chip is different, again, packaging and testing also follow the appropriate standards, such as AEC-Q002 and AEC-Q100. In addition, there are also requirements for the production plants. For example, if a series of standards such as TS16949 are to be adopted, only the product yields of such designs and productions can be guaranteed.
When it comes to the lead time, this is one of the advantages of our ADI, because the ups and downs of the auto industry will not be as big as other industries. As long as the company's forecasts and customer order management are good, we will make corresponding inventory, of course, the company The operating costs will increase. In the semiconductor industry, our company's cash flow is at the forefront. This is why our company has the strength to do the corresponding inventory. At the same time, the agents that we cooperate with are also first-line agents. Businesses will also make corresponding stocks, all of which determine our lead time is first-rate, our products are now 60% can be delivered within 4 weeks, 90% can be delivered within 8 weeks.
EEWORLD: In addition, electric vehicles are the hottest but also far-reaching issues. What is ADI's current progress? What are the main applications? Solved the problem of electric cars?
Li: The main difficulties of new energy vehicles are battery management and motor control systems. Battery technology is an important driving force for new energy vehicles. It urgently needs to reduce costs and ensure safety. At the same time, the country’s supporting infrastructure, such as charging stations, must be popularized as soon as possible; the country should also issue corresponding policies and regulations to encourage and regulate this developing industry to facilitate large-scale mass production later.
ADI has introduced lithium battery monitoring and protection system products for two technical difficulties. The system integrates lithium battery safety monitors to help users implement fail-safe circuits and build safety monitoring devices for safety environments. This new monitor provides designers with the ultimate solution they need to develop a complete battery monitoring and protection system front end. The AD7280/8280 is an integrated solution that monitors the voltage and temperature inputs of six battery cells. The device is powered by a battery pack and can provide shared or individual alarms for any of three conditions of over-voltage, over-temperature, or under-voltage. The two chips meet the AEC-Q100 and EMI standards for automotive applications. Operating temperature range is -40 to +105°C.
In the lithium battery management system, ADI's iCoupler digital isolator is also recognized by many car manufacturers and module suppliers. For example, Mitsubishi Motors has announced that it will adopt this in the lithium-ion battery-powered system of the next-generation “i-MiEV†all-electric vehicle. Products. ADI's ADuM1402W and ADuM1201W iCoupler digital isolators can be used to transmit data across safety barriers between high-voltage Li-ion battery systems and standard automotive electronic systems. The iCoupler Isolator also meets other requirements such as small size, low power consumption, and extended battery life to provide longer cruising range and longer life for the car.
In the motor control system, our DSP (BF50X) series and resolver (AD2S120X) are designed specifically for this application.
