On September 3, Guolonghui announced that the automotive electronic integrated door area drive control chip product 'CCL1100B' developed by Guoxin Technology (688262.SH) has achieved success in recent internal testing. The integrated door area drive control chip product CCL1100B successfully tested internally by the company is a specialized chip for automotive electronic door area drive control. The integrated functions mainly include: 1. Up to 6 channels of direct current motor drive, including 5 channels of built-in power tubes for functions such as rearview mirror adjustment, folding, and door lock drive, which greatly reduces the cost of customer applications. In addition, 1 channel is a built-in pre-drive H-bridge motor control module used for lifting window functions; 2. Up to 10 high-side drivers (for driving light bulbs, LEDs, and anti-glare components), all high-side drivers support constant current mode for high input capacitance LED modules; 3. Integrated rearview mirror heating drive; 4. Anti-glare control; 5. Rich physical communication interfaces, including CANFD and LIN; 6. Rich power supply modules, providing power for system MCUs and external loads (such as sensors); To meet the requirements of green applications, this chip supports two low-power modes and has programmable local and remote wake-up capabilities. The chip also has a built-in powerful thermal management module to meet various power consumption application scenarios; The MCU communicates and controls with CCL1100B through the SPI interface. The resources and configurations of this chip can meet the application requirements of vehicle-grade door area control modules and can replace corresponding products of foreign companies such as STMicroelectronics L99DZX00 series. The CCL1100B chip is designed and produced according to automotive electronic grade, and is expected to contribute to solving the problem of 'chip shortage' in China's automotive industry integrated door area control field.
