In this paper, we discuss dedicated semiconductor’s configuration, function, validity, effect, implementation method of sunroof BLDC motor control based on the LIN communication. This semiconductor is formed by SBC(System Basis Chip) which are MCU, memory, power, load control, input interface, LIN communication as a SoC(System on Chip) for controlling the sunroof logic through the sunroof motor. The package is a 48pin, VQFN and 0.13um BCD process technology is used. The MCU is consist of 32bit ARM-Cortex M3 core and Timer/UART peripheral. A power is distributed 5V and 1.5V in regulator which includes charge pump for full turn on MOSFET of 3 phase driver, LIN transceiver for communication, 3 phase gate driver for motor driving. This semiconductor can be applied sunroof system as communization device in all models. Additionally, this is a platform device for another application domain in the future, Through the optimization of controller and semiconductor, we can expect improvement of system efficiency, implementation of new function, communization, cost saving, package reduction.

For improving the EMC performance in DC-DC controller, this paper justifies the five steps in terms of H/W design. The first step is input filter design. The second step is output filter design. The third step is gate resister design. The fourth step is snubber network design. The last step is commutation capacitor design. Through these design steps, the EMC test can satisfy the international EMC standard CISPR-25 Class 5.

For the LED front lamp system, Universal Controller is gradually getting expanded in the world. For corresponding the technical trend and system optimization, we have approached in terms of vehicle level as well as LED load level. By understanding lamp system architecture and hardware functional distribution, we could make discrete LDMs into Universal LDM based on CAN communication. It enables us to control LED lamp very flexible and scalable with regardless of lamp variation depend on regional and specified option. Additionally, it is very compatible with future technologies such as pixel and matrix control in connection with autonomous driving.
