Recently, Nanxin Technology announced the launch of the ASIL-B functional safety level millimeter-wave radar power management chip (PMIC) SC6207Q, providing a more efficient and reliable power solution for intelligent driving systems.
This new product will assist vehicle-mounted millimeter-wave radar in enhancing its perception capabilities in complex environments, further promoting the development of the intelligent automotive industry.
Millimeter-wave radar, with its stable and reliable performance in rain, snow, fog, and low-light environments, has become an indispensable sensor in modern vehicles’ Advanced Driver Assistance Systems (ADAS). It works in conjunction with cameras, LiDAR, and other sensors to build a fused perception capability, significantly enhancing the performance and effectiveness of ADAS systems.
In recent years, the market demand for millimeter-wave radar has continued to grow. According to statistics, from January to July 2024, the installation volume of millimeter-wave radar in passenger cars in China has reached 6.531 million units, with an installation rate rising to 57.3%, demonstrating enormous market potential.
The SC6207Q features a 5mm*5mm QFN-28 package, integrating multiple outputs, which significantly reduces the footprint on the millimeter-wave radar PCB, improving system integration. Compared to discrete solutions, its layout is more compact and efficient. The chip integrates low on-resistance switches, which can significantly reduce energy loss when the switch is in the on state, achieving over 80% efficiency. High efficiency not only helps reduce thermal noise, enhancing the imaging accuracy and resolution of millimeter-wave radar but also prevents signal strength inconsistencies caused by voltage fluctuations, ensuring uniformity and accuracy in imaging.
The SC6207Q supports a 2.1MHz fixed frequency PWM mode, offering better noise immunity and load transient response. Its programmable spread spectrum modulation function can minimize radiated electromagnetic emissions, improving system reliability. Safe and reliable, meeting ASIL-B functional safety standards, the SC6207Q integrates diagnostic and redundancy circuits.
All outputs can achieve ±1% output error accuracy within load, line, and temperature ranges. The chip also features a window watchdog, redundant reference, BIST diagnostics, and installation ID position detection, integrating over-temperature protection and short-circuit protection, perfectly adapting to the reliability requirements of automotive environments.
With the launch of the SC6207Q, Nanxin Technology has created a diversified one-stop automotive-grade PMIC product matrix covering cameras and millimeter-wave radar, providing more comprehensive and reliable support for intelligent assisted driving and fused perception.
In the future, Nanxin Technology will continue to root itself in customer R&D scenarios, continuously iterating custom designs based on customer applications, helping to develop more efficient, highly integrated, and high-safety products in the core automotive application fields.
