<p><strong>2020年2月</strong><strong>5</strong><strong>日</strong><span><span> </span>— 推动高能效创新的安森美半导体(ON Semiconductor，美国纳斯达克上市代号：</span><a href="http://www.onsemi.cn/PowerSolutions/ir.do"><span>ON</span></a><span>)，</span><span>推出由四个</span><span>器件</span><span>组成的新系列，促进汽车</span><span>厂</span><span>商和消费者现在所期望的汽车外部和内部照明</span><span>的</span><span>高水平性能和创新功能</span><span>。</span><span>新系列专门针对低功</span><span>率</span><span>固</span><span>态照明</span><span>，</span><span>包括两个</span><span>LED</span><span>驱动器（</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;和</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;）和两个电流控制器（</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;和</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;）</span><span>。</span></p>
<p><span>为</span><span>提</span><span>升</span><span>道路安全性，汽车</span><span>厂商正</span><span>从简单的“开/关”操作转向</span><span>精密</span><span>的系统，在组合</span><span>尾</span><span>灯（RCL</span><span>）</span><span>、</span><span>转向信号灯</span><span>、</span><span>雾灯和其他外部调</span><span>节</span><span>的LED集群中结合了运动和可变强度</span><span>，以</span><span>向其他道路使用者发出更清晰和</span><span>能见度更</span><span>高的警告。</span></p>
<p><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;和</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;分别集成</span><span>了</span><span>12</span><span>个和</span><span>8</span><span>个线性可编程电流源，从而能够以每通道高</span><span>达</span><span>100</span><span><span> </span></span><span>mA的电流驱动多</span><span>串</span><span>LED。</span><span>这些</span><span>器件</span><span>提供了一系列可配置选项，包括菊花链</span><span>、照明</span><span>亮度</span><span>控制</span><span>、</span><span>电流调节</span><span>、</span><span>序</span><span>列</span><span>功能和通道组合。</span><span>NCV7685</span><span>采用</span><span>具有CRC8错误检测功能的8位I</span><span>2</span><span>C接口，可通过脉宽调制（PWM）进行</span><span>个别</span><span>输出电</span><span>流调节</span><span>，并用于</span><span>先进的</span><span>诊断</span><span>，</span><span>包括LED串</span><span>开路检测</span><span>或</span><span>欠压检测</span><span>，</span><span>还提供专用的诊断引脚</span><span>。根据特定的设计要求，可以使用</span><a href="https://www.onsemi.cn/products/power-management/dc-dc-controllers-conve…控制器</span></a><span>和/或</span><a href="https://www.onsemi.cn/products/power-management/dc-dc-controllers-conve…稳压器</span></a><span>为NCV7685供电。</span></p>
<p><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-… href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;提供稳定的宽电流范围，用于驱动一串或多串LED，仅需一个外部</span><a href="https://www.onsemi.cn/products/discretes-drivers/general-purpose-and-lo…双极晶体管</span></a><span>和一个反馈电阻</span><span>。</span><span>该驱动器提供</span><span>设计灵活性，可以在多通道系统中添加</span><span>额外</span><span>单通道</span><span>，</span><span>并通过其PWM输入支持调光功能。</span><span>NCV7691包括串开路</span><span>、短路和热关断功能，</span><span>确保基本照明的安全可靠运行。</span><span>衍生</span><span>的</span><a href="https://www.onsemi.cn/products/power-management/led-drivers/linear-led-…;提供更快的响应时间，并降低了开路负载检测的阈值。</span></p>
