SILICON LABS的电容隔离驱动器 SI8261，驱动能力可达4A，通常用于传统变频，伺服，UPS，光伏等行业。笔者遇到客户，在使用东芝的光耦隔离驱动TLP5754，做测试时，发现信号延迟过长或者存在EMI干扰等问题，怀疑是芯片本身的问题，于是推荐了SI8261BCD-C-ISR，该产品不仅可以避免上述问题，同时性能更优。SI8261BCD-C-ISR和TLP5754的对比表格如下。

由上表可知，相比光耦TLP5754，SI8261BCD-C-ISR的共模抑制比CMTI可达50KV/us，对信号的抗干扰能力更强；在可靠性方面，SI8261具有60ns的低延时时间，比驱动芯片TLP5754的延时时间低很多，可提供控制的精准度；同时SI8261的最高工作温度可高达125℃，满足系统高温应用环境，确保系统更加稳定；SI8261BCD-C-ISR的副边供电电压范围为6.5-30V，范围更宽，可适应性更强。

对于Silicon Labs SI8261BCD-C-ISR IGBT驱动芯片，世强有充足的备货及库存保障，明显的价格竞争优势。

同时用户还可在世强元件电商上一键查询库存交期及采购，同时还可快速获取Silicon Labs 的SI8261BCD-C-ISR相关数据手册、解决方案、样品支持和技术服务等。

【经验】IXDN609+脉冲变压器实现高电压应用中IGBT驱动

考虑到高压应用与成本，目前市场上常见的光耦隔离与电容隔离都存在一定的局限性。以常用的SiliconLabs隔离驱动SI8261为例，其数据手册中标称的最大工作绝缘电压仅为1140V，并不能满足例如1500V光伏逆变器的等较高直流母线电压等级应用的需求。本文主要介绍IXYS（Littelfuse收购）IXDN609+脉冲变压器实现高电压应用中IGBT驱动。

【经验】隔离驱动器Si8261做驱动电路设计时的阈值电压选取原则

目前的驱动电路的设计考虑较多的是驱动电压幅值或者驱动能力即驱动的峰值电流问题，但是作为一些做驱动电路设计的工程师而言，有时会忽略副边的欠压保护问题。本文主要介绍用Silicon Labs的Si8261系列隔离驱动器做驱动电路设计时的阈值电压选取原则。

隔离器Si8715共模瞬态抗扰度 (CMTI)是指什么？

隔离器Si8715共模瞬态抗扰度 (CMTI) 是指隔离器抑制快速共模瞬变的能力，通常测量单位是 kV/μs，共模瞬变是隔离应用中数据损坏的主要原因之一。CMTI 是隔离器Si8715非常重要的参数，因为高频瞬变会通过寄生电容，跨越隔离栅进行耦合，从而破坏数据传输。
