Silicon Labs隔离器正常使用的寿命一般是多久? 根据datasheet,60-year life at rated working voltage 现在的隔离芯片在满足隔离条件的情况下最小可以做到多小? 取决于creepage和clearance的要求。 Is it possible to substitute the feedback opto in a Flyback SMPS by our isolators or our opto emulator isolators? No.  Our optocoupler replacemet products are digital in/digital out, whereas the optocoupler is esentially an analog current in/analog current out d... Silicon Labs隔离器有哪些优势? 通信速度快,信号低延迟,集成度高,EMI性能好,采用OOK的调制方式,不会出现信号错误 ISOdriver use high frequency signal across isolation barrier. What is min on time for switch? Do you use square wave or sinusoidal? Using a square wave, the minimum pulse width is Is a propagation delay larger than TI from the spec? I only see ISO550 and it is 300ns. SI82xx is smaller. (Do you have information for TI's newer dev... Our prop delay is smaller than all competitors.  CMTI does not affect propagation delay.  When a CMTI event occurs, the output logic changes state (... Does a customer need to design based on min CMTI spec? 20kV/us for Si823x Yes, that would be our recommendation. Silicon Labs isolator CMTI doesn't seem to be better than TI and ADI.  Does CMTI performance depend on the spec definition or actual performance?  All competitors use virtually the same equipment and test methodology to determine datasheet values for CMTI.  隔离器可耐受的最高电压是多少? UL1557的隔离电压。 最大的电压,导致芯片损坏的,参考Absolute Maximum Ratings 关于隔离芯片的隔离方式,各种方式之间的差异和优缺点是什么?都有哪些适用的应用方向? 1.对比磁隔离,容隔离EMI、EMC性能更好,成本更有优势,因为磁隔离有三个die 2,对比光隔离,容隔离使用寿命长,好的高低温特性...
