【选型】国产电容隔离驱动SLMI350可匹配替换光隔QCPL-341H，延迟更低、共模抑制能力更高
充电桩等电源充电产品中有较多高压MOS或者IGBT，其门极信号需要采用光耦隔离的产品来驱动，如QCPL-341H。但随着国产化需求和高性价比的需求，工程师越来越有意使用国产产品做设计和应用，本文推荐介绍数明半导体电容隔离驱动SLMI350，可匹配替换QCPL-341H，具有更低延迟、更高共模抑制能力。以下为二者部分电性能参数对比。
图1——电性能参数对比
通过以上参数对比可知：
1、SLMI350输出部分具有高宽和更高的电源电压，能够达到40V；
2、SLMI350具有更高的延迟时间，相比QCPL-341H延迟时间小一半以上；
3、SLMI350具有更高共模抑制能力，共模抑制能力能够达到150KV/μs，相比安华高25KV/μs具有更高抗干扰能力；
4、工作温度上，SLMI350具有更宽的温度范围，能够适应更宽的环境温度；
上述电性能参数上对比，SLMI350性能上具有一定的优势。管脚定义上，SLMI350的7脚为空脚管，但不影响其应用，封装尺寸上二者也基本一致，所以无需修改PCB即可pin-pin替换使用。数明为国产品牌，相比现有进口品牌有较大性价比，是现有产品国产化，完善供应链的一个非常不错的选择。
