Major New Product | Breaking Overseas Monopoly! Nanjing Semiconductor Launches the First Fully Domestic Supply Chain Vertically Integrated High-Side Switch
On September 22, Nanjing Semiconductor (Stock Code: 688484) launched the new ASIL-D functional safety level automotive SBC SC6259XQ, applicable to 12V and 24V systems, integrating up to 7 power outputs in a single chip, featuring comprehensive output protection mechanisms, watchdog, and FCCU functions. The SC6259XQ is based on proprietary intellectual property with a fully domestic industrial chain, suitable for domain controllers, intelligent cockpits, and ADAS automotive modules. The power/logic functions of the SC6259XQ offer hundreds of configurable options, providing customers with a more generalized and highly integrated power solution.
Key Power Support for Automotive Intelligence
The SBC (System Basis Chip) is crucial for achieving automotive intelligence. As a highly integrated computing platform, the SBC can provide high-performance processors, large-capacity memory, and rich interfaces, ensuring that vehicles can process complex tasks such as assisted driving in real-time while making quick and accurate decisions. At the same time, the SBC can significantly save PCB area, extend automotive battery life, reduce static current, and lower system costs. It is predicted that by 2030, the global SBC chip market will exceed $55 billion.
The SBC needs to manage multiple power rails, providing efficient and stable power for different devices, while also having fault detection and protection functions to ensure high system reliability. Nanjing Semiconductor, with its deep accumulation in the power field, has launched an ASIL-D functional safety level SBC that can adapt to different voltage system platforms, achieving up to 7 outputs, providing a high-performance domestic option for advanced driver assistance systems.
Highly Integrated Single Chip
The SC6259XQ adopts an 8mm*8mm QFN-56 package, integrating 5 DC-DC converters and 2 LDOs in a single chip. The integrated DC-DC converters include 1 synchronous high-voltage buck controller (VPRE), 1 asynchronous low-voltage boost converter (LVBOOST) with an integrated low-side switch, and 3 low-voltage buck converters (LVBK). The highly integrated design significantly reduces the area of power components on the PCB. Nanjing Semiconductor provides standardized reference designs for the SC6259XQ, eliminating the need for manual optimization of noise, timing, dynamics, software initialization, etc., reducing design complexity and development cycles. The SC6259XQ supports I2C/SPI configuration, collaborating with the MCU to manage power strategies.
High Reliability with Fully Domestic Industrial Chain
The SC6259XQ is developed according to the ISO26262 ASIL-D functional safety process, compliant with AEC-Q100 Grade 1 standards, supporting Logic Built-In Self-Test (LBIST) and Analog Built-In Self-Test (ABIST) to verify the correct functionality of safety logic and analog monitoring. It can be controlled via a 32-bit SPI or 40-bit I2C interface, providing PGOOD, reset, fail-safe output, and interrupt functions for diagnostics. To achieve better EMC performance, the SC6259XQ also integrates frequency synchronization, spread spectrum, slew rate control, and frequency fine-tuning functions.
The SC6259XQ has higher load-driving capability and a wider configurable output voltage range. This product is based on the company’s proprietary intellectual property and a fully domestic industrial chain, helping OEMs accelerate development cycles and enhance the competitiveness of end products.
Multi-Functional Flexible Applications
The SC6259XQ offers different numbers of LVBK, FCCU functions, and various VMONx channel options, featuring multiple voltage monitoring functions, configurable simple or challenging watchdogs, FCCU monitoring functions with fault recovery strategies, and external integrated circuit monitoring capabilities. The SC6259XQ includes 2 wake input pins (WAKE1/2); it features an analog multiplexer (AMUX) for the MCU to achieve redundant monitoring; it can also synchronize power-up with other PMICs, facilitating system expansion.
