<p><span>Diodes<span> </span></span><span>公司</span><span><span> </span>(Nasdaq</span><span>：</span><span>DIOD)<span> </span></span><span>推出</span><span><span> </span></span><a href="https://www.diodes.com/part/AL5873Q"><span>AL5873Q</span></a><span><spa…;，</span><span>扩大支持汽车外部灯具的装置组合规模</span><span>，</span><span>用以简化汽车后侧灯具组的设计作业</span><span>。</span></p>
<p><span>这款</span><span>符合汽车规格</span><span><span> </span></span><span>AEC-Q100 G</span><span>rade 1<span> </span></span><span>认证</span><span>的装置，额定运作环境温度为</span><span><span> </span>125°C</span><span>，满足下一代汽车设计的要求，同时还能节省能源和空间，降低整体系统成本。</span><span>AL5873Q<span> </span></span><span>的每个信道可以驱动高达</span><span><span> </span>250mA<span> </span></span><span>的电流，并且通过两个参考电阻进行设定，这两个电阻连接到驱动器</span><span><span> </span>IC<span> </span></span><span>的</span><span><span> </span>REF1<span> </span></span><span>及</span><span><span> </span>REF 2<span> </span></span><span>接脚。支持两种不同的</span><span><span> </span>LED<span> </span></span><span>电流位准，可以更为简化照明系统</span><span><span> </span>–<span> </span></span><span>原因在于相同的</span><span><span> </span>LED<span> </span></span><span>可以用在后侧灯具组的尾灯及煞车灯。这么一来便大幅降低了物料清单</span><span><span> </span>(BOM)<span> </span></span><span>的成本。</span></p>
<p><span>AL5873Q<span> </span></span><span>具有模拟和主要</span><span><span> </span>PWM<span> </span></span><span>调光控制功能，支持最大</span><span><span> </span>1kHz<span> </span></span><span>的</span><span><span> </span>PWM<span> </span></span><span>频率。以低电流位准驱动</span><span><span> </span>LED<span> </span></span><span>时，</span><span>PWM<span> </span></span><span>调光功能对于提高电流精度来说极为重要。每个通道上的电流皆调节至</span><span><span> </span>±4%<span> </span></span><span>的公差范围内，让后侧灯具组合拥有更佳的信道</span><span>-</span><span>信道搭配结果。若未侦测到</span><span><span> </span>PWM<span> </span></span><span>讯号，</span><span>AL5873Q<span> </span></span><span>会进入待机模式，以节省电力。</span></p>
<p><a href="https://www.diodes.com/part/AL5873Q"><span><span>AL5873Q</span></span><…，其双向</span></span><span><span><span> </span>(</span></span><span><span>输入</span></span><span><span>/</span></span><span><span>输出</span></span><span><span>)<span> </span></span></span><span><span>故障接脚可标记任何故障，并且允许多达四个装置将其故障接脚接在一起，以便</span></span><span><span>共同通报所发现的任何故障。而在其保护功能中，若是超过其规定的阈值温度，内部接面温度监测电路会降低</span></span><span><span><span> </span>LED<span> </span></span></span><span><span>的电流。除了这种热折返，还有热关断和</span></span><span><span><span> </span>LED<span> </span></span></span><span><span>灯串开路</span></span><span><span>/</span></span><span><span>短路保护机制，以及输入欠压锁定等功能。</span></span></p>
<p><span><span>AL5873Q 采用紧凑型 16 接脚 TSSOP 封装，支持 PPAP 文件，且以 IATF 16949 标准认证的生产设施制造。</span></span></p>
