Achieve responsive/unresponsive FOC control, helping to solve the "chip shortage" problem in the automotive industry.

The company's independently developed new-generation automotive electronic BLDC (brushless DC) motor drive control high-performance chip CBC2100B has successfully completed internal testing and has been sent for samples to key customers. This chip is developed based on the 130nm BCD process and can be compared with Infineon's TLE988x/9x series. This marks a crucial step for Guoxin Technology in the field of high-end automotive electronic MCU integrated drive control. 

1. Adapting to the trend of automotive electrification, seizing the high ground in BLDC drive chips
As the global automotive industry accelerates its transformation towards electrification and intelligence, BLDC motors, with their advantages of high efficiency, long lifespan, and low noise, are widely used in the thermal management system, chassis actuators, and body control of new energy vehicles. According to market research data, the global market size of BLDC motor main control and drive chips is expected to reach 12.76 billion US dollars by 2032, with a compound annual growth rate of 13.2%. At the same time, the demand for this core chip for independent control in China's automotive industry is becoming increasingly urgent. 
The CBC2100B launched by Guoxin Technology precisely responds to the aforementioned market trends and the demand for domestic products. This chip is applicable to automotive electronic scenarios such as water pumps, oil pumps, and air conditioning fans, and can also be extended to BLDC motor drives and electric equipment applications in the industrial control field. 
II. Core Technology: A Balance between High Integration and High Security
The CBC2100B demonstrates the current mainstream technical direction of BLDC motor drive chips - integrating the control logic, drive circuitry, and protection functions to a high degree, significantly reducing the BOM cost and design complexity of the system. 
The main technical characteristics of this chip are: 
Advanced BCD process platform: Developed based on 130nm BCD (Bipolar-CMOS-DMOS) technology, the input voltage can reach up to 28V. It is compatible with automotive 12V/24V systems and industrial applications. 
Powerful processing and driving capabilities: Embedded 32-bit CPU core, supports programmable control; Integrated PWM module, dead time can be programmed separately; Integrated BEMFC module, enables sensorless control; Gate driver can support a maximum driving current of 350mA, output current capacity can be programmably controlled. 
Rich communication and security features: Embedded with LINFlex, CANFD (built-in transceiver) and SPI and other automotive standard communication interfaces; Supports random numbers and AES-128 encryption algorithm, enabling secure boot. 
Comprehensive protection mechanism: Supports overvoltage/undervoltage, overcurrent, overtemperature and external MOS short-circuit monitoring functions for motor applications, significantly enhancing system reliability. 
Vehicle-grade high reliability: Designed and manufactured in accordance with automotive electronic Grade 0 standards and functional safety ASIL-B standards, with the junction temperature range meeting the strict requirements of vehicle-grade environments. 
Flexible packaging options: Offer various packaging forms such as LQFP64/TQFP64/LQFP48/TQFP48, which can meet the PCB layout requirements of different application scenarios. 
III. Alternative Meaning: Benchmarking against international leaders, filling domestic gaps
For a long time, the high-end automotive motor drive chip market has been dominated by international giants such as Infineon, Texas Instruments, and NXP. The CBC2100B can be compared to Infineon's TLE988x/9x series chips for BLDC applications, achieving both-sensor, single-resistor/double-resistor FOC (field-oriented control) and non-sensor BLDC control schemes. 
Guoxin Technology stated that the company holds complete independent intellectual property rights for this chip. The successful development of this product has further enriched the company's product line of high-end automotive electronic MCUs with integrated drive control functions, and is expected to make a substantive contribution to solving the "shortage of chips" problem for high-end MCUs in China's automotive industry, especially in the field of new energy vehicles.
