【应用】AQ24CANFD TVS阵列帮助汽车LED前照灯实现高可靠防护电路

时间： 2019-01-26 来源：Littelfuse

技术问答

相对于传统的汽车前大灯，LED有众多的优势和特点：单色性突出、抗震、寿命长、响应时间短、高效率低能耗、绿色照明等等。在众多技术优势条件下，特别是当今国家提出的节能减排的政策推动下，作为高功率的汽车前照灯-卤素灯泡，必将被LED前照灯所替代。LED前照灯可靠运行需要性能优异的驱动电源，所以设计性能优异、可靠性高的驱动电源是众多汽车灯具厂家一直在研究的课题。

通常情况下，汽车LED灯采用恒流控制设计，一般总功率在20W左右。考虑到散热要求，一般会选用高效率的DC/DC变换器，像BUCK、BOOST或者BUCK-BOOST电路拓扑进行恒流控制。具体输出电压的多少根据LED数量和调光的要求进行适应性配置。下图是具有降压功能的BUCK调光电路。

以常见的LED前大灯驱动设计要求为例，一般的规格需要如下：

1.输入电压：直流12V-24V通用(DC无极性)
2.输出电流：单电源设计，输出3000MA
3.输出功率：30W

4.控制方式：恒流控制

通常为了保证LED驱动可靠的运行，输入级的防雷击、浪涌、ESD等的EMC电路防护必不可少。如下图所示，LED驱动的前端EMC防护电路。

TVS管由于其出色的响应速度（亚纳秒级）和卓越的瞬态吸收功率而被广泛的应用在EMC的防护中。对于汽车级应用的TVS管，LITTELFUSE公司设计了AQ24CANFD系列的TVS阵列，专门用于汽车级的TVS防护。该系列的TVS管可以重复吸收超过IEC61000-4-2国际标准的电压闪变而不会有性能的下降，并且可以安全的在非常窄的钳位电压范围里吸收3A浪涌电流。主要的技术指标如下：

说明：

1.传输线脉冲 (TLP)，宽度为 100ns，上升时间为 2ns，平均窗口 t1 = 70ns 至 t2 = 90ns

应用分析：

AQ24CANFD反向峰值电压、吸收浪涌能力、钳位电压非常匹配车规级LED驱动电源的要求，-40°C到150°C的军工级别的工作范围也能胜任汽车的各种使用环境。

另外AQ24CANFD不但可以用于汽车的LED前大灯防护电路，也可以用于汽车电气系统其他需要做电压瞬态抑制的地方。

【应用】力特TVS二极管SMAJ5.0CA用于伺服驱动器IO口保护，峰值脉冲功耗高达600W

主控单元是伺服驱动系统的核心，它与外部连接的IO口容易收到雷击、浪涌等影响，严重的会破坏主控的IO口。有客户在设计总线型伺服驱动器时，需要TVS二极管用于主控单元中IO口的保护。根据需求，我们推荐了力特的TVS二极管SMAJ5.0CA，反向峰值电压VRWM。
