摘要

横向绝缘栅双极晶体管(light)在功率集成电路中的单片集成是当前的一个研究课题。过流保护方案通常需要作为电源集成电路功能的一部分来构建。保护电路需要区分各种故障情况，并根据设备安全操作区域(SOA)的限制做出不同的反应。同时，电路也要相对简洁，适合集成。本文提出了一种简洁的栅极驱动保护电路，提供了完整的过流保护功能。实验结果验证了该电路的性能。讨论了该电路在横向IGBT上的实现，并给出了仿真结果。

Design of lateral IGBT protection circuit for smart power integration

Monolithic integration of lateral insulated gate bipolar transistor (LIGBT) in power integrated circuits is a current research topic. The overcurrent protection scheme is usually necessary to be built as part of the functions in power integrated circuits. The protection circuit requires to distinguish various fault conditions and to react differently based on the device safe operating area (SOA) limitation. At the same time, the circuit should also be relatively concise and suitable for integration. In this paper, a concise gate drive protection circuit is proposed to provide the complete function of overcurrent protection for LIGBT. The performance of the circuit was verified with experimental results. The implementation of the proposed circuit on lateral IGBT is also discussed and the simulation results are presented.
