摘　　要：在自主研发国内BCD高压工艺的同时,设计并实现了一款用于42″数字电视PDP平板显示屏的扫描驱动芯片.该芯片及其制作工艺不仅实现了Bipolar,CMOS和高压功率DMOS器件的良好兼容(BCD工艺),而且采用工艺与电路设计互相匹配的交互方式完成了高低电平位移电路和高压输出驱动电路及其器件的设计,有效提高了芯片的性能,减小了芯片的面积.测试结果表明该芯片功能正常,性能良好,各项技术参数基本达到国外同类产品指标.在低压5V和高压160V的情况下工作,完全满足42″PDP显示系统的需求.Based on independent research of bipolar-CMOS-DMOS high voltage processes,a new plasma display panel scan driver IC for 42＂ digital TVs is implemented. The high voltage power devices are integrated and compatible with ordinary CMOS and Bipolar devices and work in low voltage. The level-shifter driver circuit matches this process perfectly,which greatly enhances its performance and reduces the chip size. The test results show that the performance of this PDP scan driver IC is perfect and its technical parameters achieve the same level as those of foreign products. It fully satisfies the demands of the 42＂ PDP system under the condition of a low power supply of 5V and a high power supply of 160V .
