<p><span>在计算、物联网</span><span lang="EN-US">(IoT)</span><span>、电动工具、消费类、医疗保健和移动终端等应用领域，对于采用</span><span lang="EN-US">2</span><span>至</span><span lang="EN-US">4</span><span>节</span><span lang="EN-US">Li+</span><span>电池供电的手持式设备，用户安全是设计师的首要考虑因素。存在缺陷或损坏的电池可能发生内部电池泄漏，随着这种情况逐渐恶化，可能引发火灾、爆炸等严重事故。直接危及了消费者的安全，当然也损害了制造商的品牌效益。严格的工厂筛查可有效防止发生泄漏的电池从工厂流向社会。但截至目前，尚无方案可以检测电池在正常使用期间产生的自放电。</span><span lang="EN-US">MAX17320</span><span>弥补了这一空缺，能够及时向系统发出报警，以便在发生危险隐患之前关闭发生泄漏的电池。除此之外，这款</span><span lang="EN-US">IC</span><span>拥有最先进的电池保护功能，可根据不同的温度区域对电压和电流门限进行微调。</span><span lang="EN-US">IC</span><span>也提供二级保护，在严重故障条件下，通过协助二级保护器或熔断保险丝永久断开电池。</span></p>

<p><span>与所有移动设备一样，制造商的目标之一是开发出电池寿命更长产品。电池供电设备需要更高精度的</span><span lang="EN-US">SOC</span><span>信息，以精确估算剩余运行时间。作为具有</span><span lang="EN-US">ModelGauge m5</span><span>算法系列</span><span lang="EN-US">IC</span><span>的其中一员，</span><span lang="EN-US">MAX17320</span><span>可提供业界最高精度的</span><span lang="EN-US">SOC</span><span>，允许设计师实现最长的系统运行时间，且避免过早或突然关闭系统。</span><span lang="EN-US">MAX17320</span><span>可工作在超低功耗模式，支持系统在唤醒时即时读取</span><span lang="EN-US">SOC</span><span>信息；在运输或储存期间无需断开电池。</span><span lang="EN-US">MAX17320</span><span>拥有业界最低</span><span lang="EN-US">IQ</span><span>，比领先的竞争产品低</span><span lang="EN-US">85%</span><span>，支持较长的产品储存期限。</span></p>

<p><strong><span>主要优势</span></strong></p>

<ul>
<li><strong><span>可靠保护：</span></strong><span>可监测异常电压、电流和温度条件，确保</span><span lang="EN-US">2</span><span>至</span><span lang="EN-US">4</span><span>节</span><span lang="EN-US">Li+</span><span>电池供电系统的安全充电和放电。内部自放电检测为系统提供预警并切断存在危险隐患的电池。凭借</span><span lang="EN-US">SHA-256</span><span>安全认证防止克隆，为每个电池提供唯一或动态密钥。</span></li>
<li><strong><span>最高精度：</span></strong><span>与竞争产品相比，</span><span lang="EN-US">ModelGauge m5</span><span>算法的电池</span><span lang="EN-US">SOC</span><span>精度提高</span><span lang="EN-US">40%</span><span>。</span></li>
<li><strong><span>最低</span></strong><strong><span lang="EN-US">IQ</span></strong><strong><span>：</span></strong><span>支持较长的产品储存时间和运行时间，工作状态的</span><span lang="EN-US">IQ</span><span>比最接近的竞争产品低</span><span lang="EN-US">85%</span><span>。</span></li>
