In recent years, the electronic and electrical architecture of new energy vehicles has been continuously upgraded, and the level of automotive electrification has gradually increased. This has led to a much greater demand for analog chips than in traditional vehicles. Driven by this demand, automotive-grade power management chips have become the foundational support for the intelligence and electrification of automobiles.

SCT focuses on power management chips, providing solutions in three main areas: power conversion, power control, and system integration. These solutions cover six product lines: switching power supplies, linear power supplies, power control, intelligent power switches, system integration solutions, and power modules. After confirming the strategic direction of new energy vehicle electronics, SCT has actively promoted the accelerated development and certification of automotive chips.

Application Scenario Analysis

SCT has recently launched more than 10 automotive-grade power chip products, including LDOs, buck converters, boost/buck-boost/flyback controllers, MOSFET drivers, power protection devices, integrated PMIC products, etc. These products provide comprehensive power solutions for various automotive applications, including intelligent cockpits/ADAS domains, vehicle power domains, and body domains.

Intelligent Cockpit/ADAS Domain Application Solutions

Domain controllers are the products with the highest demand for power in new energy vehicles. Currently, SCT’s power solutions can meet approximately 80% of customer power application requirements. At the same time, SCT continues to expand its related product offerings, drive technological upgrades, and ensure stringent quality control to meet automotive-grade certifications.

Vehicle Power Domain Solutions

SCT provides complete solutions for auxiliary power sources in the vehicle power domain. The newly launched SCT81620/1Q boost/SEPIC/flyback controllers offer superior performance as domestic alternatives, helping users address issues such as EMI and overcurrent protection in existing products.

Automotive-grade Power Management Chips

Currently, the chips in the solutions that have been mass-produced have received AEC-Q100 certification.

AEC-Q100 testing is used to prevent potential faults or conditions that may arise in products. Each chip is rigorously confirmed for quality and reliability, ensuring that the manufacturer’s product datasheets, usage goals, and function descriptions align with the initial requirements and that performance remains consistent during continuous use.

Compared to the first generation, SCT’s second-generation buck converters, SCT2434Q/SCT2464Q, are smaller and more efficient. They use second-generation ultra-low static power ULQ technology to achieve 80% efficiency at a 1mA load, with light-load efficiency at internationally advanced levels. Multiple technologies, such as multi-step gate drive and switching without ringing, combine to provide exceptional EMI handling. Several patented technologies address pain points in automotive applications, such as light-load inductor noise and overvoltage during mode switching.
