In recent years, the electronic and electrical architecture of new energy vehicles has been continuously upgraded, the level of automobile electronization has gradually improved, and the demand for analog chips is far greater than that of traditional automobiles. Under the pull of this demand, the vehicle gauge level power management chip has become the basic support for automobile intelligence and electrification.

Xinzhou Technology focuses on power management chips, providing solutions in three directions: power conversion, power control and system integration, covering six product lines: switching power supply, linear power supply, power control, intelligent power switch, system integration solution and power module. After confirming the strategic direction of new energy automotive electronics, we actively promoted the accelerated development and certification of automotive chips.

Application scenario analysis

Core Technology recently launched more than 10 types of vehicle gauge power chip products: LDO, buck converter, boost/lift/flyback controller, MOS tube driver, power protection device, integrated PMIC products. It provides a full range of power solutions for various on-board applications such as intelligent cockpit /ADAS domain applications, on-board power domain, and body domain.

智能座舱/ADAS域应用解决方案

Domain controllers are the most demanding products in the power supply category of new energy vehicles. At present, Xinzhou Technology has power supply solutions that can meet nearly 80% of customers' demand for power application categories. At the same time, we are also constantly enriching related products, promoting technological upgrading, and strictly controlling the quality to pass the vehicle regulation certification.

车载动力域解决方案

Xinzhou Technology can provide customers with complete power domain auxiliary source solutions. The newly launched SCT81620/1Q boost /Sepic/ flyback controller can provide users with better performance of domestic leveling solutions, to help users solve the existing products EMI and overcurrent protection and other pain points.

Car level power management chip

At present, the mass-produced chips in the solution have been certified by AEC-Q100.

AEC-Q100 test prevents various conditions or potential failure of the product, carries out strict quality and reliability confirmation for each chip case, and confirms whether the product data sheet, purpose of use, function description, etc. proposed by the manufacturer meets the initial required function, and whether the function and performance can be consistent after continuous use.

Compared with the first generation, the second generation buck converter SCT2434Q/SCT2464Q is small in size and high in efficiency. The second generation of ultra-low static power ULQ technology is used to achieve 80% efficiency at 1mA load, and the light-load efficiency is in the international advanced level; Through the combination of multi-step gate drive technology to realize the switch no ringing and other technologies, to provide the market with excellent EMI processing capabilities. With the support of a variety of patented technologies, it solves the pain points such as abnormal inductance and overvoltage during mode switching in vehicle applications.
