A Novel High-Voltage Detector Integrated into SPIC by Using FFLR
摘要
Abstract
A novel high-voltage detector that can be integrated into SPIC (Smart Power IC) is proposed. The structure is designed on the basis of normal junction terminal technique of FFLR (Floating Field Limiting Rings) system. The field-limiting ring as a voltage divider,is used to optimize the surface field. The voltage of main junction increases from 0 to a high value,while the utmost ring is designed to vary within a small range,which can be handled by using low voltage logic circuits. An example of 400V rings system is analyzed and simulated for this structure. The results prove that the high voltage detector can detect high voltage in SPIC. The structure can be integrated into SPIC. Besides,it is compatible with CMOS or BCD(Bipolar CMOS Dmos) technology,without any additional processes required.关键词
