<p><span>Alleg</span><span>ro</span><span>电流传感器总监</span><span>Shaun Milano</span><span>介绍</span><span>说</span><span>：</span><span>“</span><span>在</span><span>过去</span><span>20</span><span>多年</span><span>中</span><span>，</span><span>Al</span><span>legro</span><span>一直</span><span>是</span><span>电流</span><span>感测</span><span>解决方案的领先创新者，</span><span>并</span><span>率先</span><span>推出</span><span>了</span><span>无芯差分霍尔效应电流</span><span>感测</span><span>技术</span><span>。</span><span>我们的新型</span><span>ACS37610</span><span>能够</span><span>使</span><span>客户</span><span>以非常经济</span><span>高效</span><span>且</span><span>简单</span><span>的方式准确测量数百或数千安培的电流。</span><span>Alleg</span><span>ro</span><span>基于霍尔</span><span>效益</span><span>的差分传感器具有出色的抗杂散</span><span>场</span><span>能力，而无需竞争解决方案所需</span><span>的屏蔽</span><span>，</span><span>这</span><span>些</span><span>屏蔽</span><span>会减慢响应速度</span><span>，</span><span>并在系统中增</span><span>大</span><span>非线性误差</span><span>。</span><span>”</span></p>
<p><strong>面向</strong><strong>苛刻</strong><strong>电流</strong><strong>感测</strong><strong>应用的</strong><strong>全</strong><strong>新</strong><strong>高级</strong><strong>功能</strong></p>
<p><span>ACS37610是电动汽车高压牵引电机逆变器</span><span>、</span><span>48V</span><span>/</span><span>12V辅助逆变器</span><span>、</span><span>异构冗余电池监控</span><span>、</span><span>过流检测</span><span>、</span><span>智能保险</span><span>、</span><span>配电单元（PDU）和电源</span><span>等</span><span>应用</span><span>的</span><span>最</span><span>佳</span><span>选择。</span><span>ACS37610</span><span>具有</span><span>250</span><span>kHz带宽</span><span>、</span><span>专用</span><span>过流和过热故障引脚以及</span><span>完整</span><span>内置诊断功能</span><span>，</span><span>使其成为</span><span>安全至关重要</span><span>应用的理想之选。</span></p>
<p><span>ACS37610采用</span><span>了</span><span>先进的差分传感技术，与ACS37612相比，信噪比（SNR）提高了2.5倍，噪声降低了2倍。较低的噪声可提供精</span><span>准</span><span>转矩控制所需的</span><span>高</span><span>分辨率，而</span><span>ACS37610</span><span>高</span><span>4倍</span><span>的</span><span>灵敏度范围可实现灵活的</span><span>汇流排</span><span>和PCB设计。</span></p>
<p><span>作为</span><span>一项</span><span>非</span><span>强制性</span><span>措施</span><span>，</span><span>汇流排</span><span>或PCB铜走线的</span><span>浅槽</span><span>设计</span><span>可进一步改善系统的</span><span>信噪比</span><span>。</span><span>ACS37610具有更大的</span><span>2.5mm</span><span>霍尔元件间距</span><span>（</span><span>ACS37612</span><span>则为</span><span>1</span><span>.8</span><span>mm</span><span>）</span><span>，可容纳更宽的</span><span>浅槽</span><span>，从而几乎不会</span><span>出现</span><span>热性能下降和热点</span><span>等</span><span>问题</span><span>。</span><span>相对于</span><span>汇流排</span><span>，</span><span>ACS37610</span><span>能够</span><span>以水平或垂直方向安装，从而在机械装配中</span><span>具有</span><span>非常</span><span>高</span><span>灵活性。</span></p>
