<p><span>国内领先的驱动类</span><span lang="EN-US">IC</span><span>一站式提供商数明半导体持续深耕隔离驱动领域，于近日正式发布国内首款单通道带</span><span lang="EN-US">DESAT</span><span>保护功能的</span><span lang="EN-US">IGBT/SiC</span><span>隔离驱动器</span><span lang="EN-US">SLMi33x </span><span>。该芯片内置快速去饱和</span><span lang="EN-US">(DESAT) </span><span>故障检测功能、米勒钳位功能、漏极开路故障反馈、软关断功能以及可选择的自恢复模式，兼容光耦隔离驱动器，为客户工程师提供高质量、高性能的替代方案。</span></p>

<p><span>通过采用业界领先的双电容隔离技术和</span><span lang="EN-US">“OOK”</span><span>传输技术，</span><span lang="EN-US">SLMi33x</span><span>实现了</span><span lang="EN-US">5kVrms</span><span>的隔离电压和高达</span><span lang="EN-US">10kV</span><span>的隔离浪涌电压，并具有超过</span><span lang="EN-US">100kV/us (Min.)</span><span>的共模瞬态抗扰度（</span><span lang="EN-US">CMTI</span><span>），满足了</span><span lang="EN-US">SiC</span><span>功率器件对</span><span lang="EN-US">CMTI</span><span>的高要求，保证了在极端恶劣工作环境下的可靠性和稳定性。</span><span lang="EN-US">SLMi33x</span><span>的</span><span lang="EN-US">DESAT</span><span>阈值为</span><span lang="EN-US">6.5V</span><span>或</span><span lang="EN-US">9V</span><span>，其最大驱动电流有</span><span lang="EN-US">1.5A</span><span>，</span><span lang="EN-US">2.5A</span><span>和</span><span lang="EN-US">4.0A</span><span>三档，可广泛应用于电机驱动、大功率变频器、不间断电源（</span><span lang="EN-US">UPS</span><span>）、</span><span lang="EN-US">EV</span><span>充电、逆变器等应用场景。</span></p>

<p><strong><span lang="EN-US">SLMi33x</span></strong><strong><span>性能优势</span></strong></p>

<ul>
<li><span>抗负压能力更强</span></li>
<li><span>最大延时更短</span></li>
<li><span>输入侧和输出侧的电压范围更宽</span></li>
<li><span lang="EN-US">CMTI</span><span>值更高，抗干扰能力更出色</span></li>
</ul>

<p><span lang="EN-US">SLMi33x</span><span>在<span lang="EN-US">IGBT</span>三相桥式的典型应用电路如图<span lang="EN-US">1</span>所示。正常工作时，<span lang="EN-US">Anode</span>和<span lang="EN-US">Cathode</span>接收控制器的控制信号，<span lang="EN-US">VOUT</span>输出驱动信号来驱动<span lang="EN-US">IGBT</span>的开通和关断。当发生短路保护时候，<span lang="EN-US">IGBT</span>的<span lang="EN-US">VCE</span>电压通过<span lang="EN-US">DESAT</span>检测，当<span lang="EN-US">DESAT</span>上的电压高于<span lang="EN-US">6.5V</span>或<span lang="EN-US">9.0V</span>时，即关掉<span lang="EN-US">VOUT</span>输出并传到控制端侧并拉低<span lang="EN-US">FAULT</span>。</span></p>
