Abstract: 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 .
