【选型】比起NXP PESD1CAN，使用TVS管SP3022-01ETG有效提升USB2.0端口的BCI抗扰能力

时间： 2020-01-17 来源：世强

技术问答

瞬态电压抑制二极管（TVS）是一种抑制有害高压脉冲的小型器件，当它的两端经受瞬间的高压冲击时，能以亚纳秒的速度把其自身两端间的阻抗值由高阻抗变为低阻抗，以吸收一个瞬间大电流到大地，从而把它的两端电压箝制在一个预定的数值上，以保护后面的电路免受瞬态高压尖峰脉冲的冲击。

不同的TVS适用于不同电路，甚至不同的TVS适用于卖给不同客户的相同电路（原因是不同的客户对可靠性的要求不同），因此TVS的选型对电路设计者来说至关重要，本文通过一款汽车音响设计案例来对此进行说明。

这款车载音响产品中USB2.0总线的接口电路如下，图1的左侧为接口，右侧为USB OTG模块（此模块内嵌于SOC中），用于和外部的产品进行消息的处理和收发。图中红圈位置是NXP的双通道TVS，型号为PESD1CAN，它靠近接口放置以便高压脉冲能量能通过它自身就近快速的释放到产品主板的地。

图1 USB2.0电路图

上图的USB2.0电路，当执行大电流注入（BCI）测试时USB2.0通讯中断，BCI测试停止时需要手动插拔U盘后通讯才能恢复，BCI的测法是把干扰电流通过耦合夹耦合到产品的线缆上（USB2.0线属于车载音响的线缆之一），因走线有阻抗（芯片输入阻抗），当沿着线缆进入产品内部芯片时就形成了高压脉冲形成干扰，通用的BCI法规如图2所示。

图2 通用汽车BCI法规

经过仔细分析后，笔者换上LITTELFUSE的单通道TVS产品SP3022-01ETG重新进行测试（换上SP3022-01ETG后的电路图如图3所示），结果如预期那样，可以通过通用汽车BCI测试，为了避免个体差异现象，我们又拿了两台样机都换上SP3022-01ETG，也无一例外的通过了通用汽车BCI测试。

图3 换上SP3022-01ETG后的USB2.0电路

为何会有这样的不同结果？

我们首先来比较下才有上述不同TVS后电路图的布线区别（见图4图5），可以看到采用单通道TVS管SP3022-01ETG时USB2.0的差分线是完全对称分布的，而采用NXP 双通道TVS管PESD1CAN时USB2.0的差分线无法做到对称分布，因此其阻抗会发生变化，信号质量会变差，噪声余量变小，加上走线对称性变差，在外界BCI高压脉冲的干扰下信号质量会恶化从而引起抗干扰性能下降，这是导致BCI测试中USB2.0通讯中断的原因之一。

图4 USB2.0布线图（采用NXP 双通道TVS管PESD1CAN）

图5 USB2.0布线图（采用单通道TVS管SP3022-01ETG）

再来对比下两者的参数：

图6 TVS参数对比

通过对比我们发现，两种TVS的峰值电流一样，2颗0402的SP3022-01ETG跟1颗SOT23的PESD1CAN尺寸也差不多，差异点主要有三点：

（1）电容量：PESD1CAN的电容量11pF，而Littelfuse的这款SP3022-01ETG只有0.35pF，这么低的电容量可以最小化对信号质量的影响；

（2）击穿电压：SP3022-01ETG的击穿电压只有9V，远远小于PESD1CAN的24V，这使得SP3022-01ETG在更低的电压脉冲时就开始起作用对噪声电流进行泄放；

（3）钳位电压：PESD1CAN是40V，而Littelfuse的这款TVS产品钳位电压是12V，在更低的电压就可以钳位。

通过以上三点对比再加上前面的布线情况对比可以很清楚的看到，Littelfuse的这款TVS产品SP3022-01ETG，在BCI抗扰方面具有更好的优势，是车载音响USB2.0线路BCI保护的首选器件。

【技术浅谈】TVS的选型计算你做对了吗?（续）

TVS的选型计算介绍。上一篇写的计算方法针对的是单次的浪涌，比如Surge test一般两次浪涌之间会有30~60 s的间隔时间，这意味着TVS有足够的时间去把吸收的浪涌能量给耗散掉，不会因为热累积而导致TVS温度过高而损坏。但是，现实中还有一些情况是会有重复浪涌的。
