摘　　要：为了提升系统的可靠性,并有效抑制热插拔过程中的浪涌,设计了基于LTC4364-2的热插拔保护电路。首先对大型系统中多模块组合结构的热插拔应用需求进行分析,然后介绍热插拔保护电路的设计过程,并对设计电路进行测试验证。验证结果表明:该设计电路不仅可有效抑制热插拔过程中的浪涌电流,而且能够有效避免60 V/DC持续高压对负载的损伤。该保护电路已在实际安全控制系统中投入使用,通过系统验证了其实用性和稳定性。In order to improve the reliability of the system, and to effectively inhibit the surge in the hot swap process, the hot plug protection circuit based on LTC4364-2 is designed. In this paper, we analyze the demand of multi module structure in the large scale system, and then introduce the design process of the hot swap protection circuit. The verification results show that the designed circuit can not only effectively inhibit the surge current in the hot plug, but also can effectively avoid the damage of the 60 V/DC continuous high voltage to the load. The protection circuit has been put into use in the actual safety control system, and the use of the system is verified by the system.
