【应用】基于Littelfuse ESD保护器件的ESATA接口保护方案
ESATA是SATA接口的扩展版,主要用于移动硬盘和电脑等相关产品。为了防止静电干扰导致数据传输异常或者失败的情况,ESATA接口需增加ESD保护器件,因接口的传输速率高达3Gbps,故需求超低容值1pF以内的ESD器件。
图1:ESATA的ESD保护示意图
根据芯片的引脚布局,推荐LITTELFUSE ESD器件SP3003-02(SP3003-02XTG),主要用于信号收发接口RX-、RX+、TX-和TX+保护,布线和接法可参考原理示意图。
SP3003-02XTG是6V的双路单向TVS,封装是小型的DFN-6L,可实现保护的情况下占用很小的接口的布板面积,实现接口小型化。接触静电±8KV和空气静电等级±15KV、静电等级高。低电容0.65pF,小于1pF,能快速响应静电干扰以保护接口芯片。根据IPP*VCmax得到37.5W的高功耗,产品能承受的瞬态功耗高,产品具有高稳定性。

USB接口和SIM卡接口防静电使用的ESD器件要求有不同吗?
基本上是没有不同的,SIM卡接口有四路,分别为VBUS、DATA、CLK、RESET,每路均需要做ESD防护,而USB接口中的USB1.1/USB2.0也是四路,分别为VBUS、D+、D-、GND,其中除GND外均需要做ESD防护,不过USB3.0接口在USB1.1/USB2.0原四路信号的基础上,有新增SSTX+/SSTX-、SSRX+/SSRX-,这四路高速信号均需要做ESD防护。且工作电压VBUS也兼容(5V),如果每路均选用一颗双向的TVS管,要求直接接触的ESD耐压大于±8KV即可,当然,可以选择1颗四路双向TVS阵列做ESD防护,或者2颗双路双向TVS阵列。针对SIM卡ESD防护设计做选型推荐如下,为littelfuse(力特)保护器件:USB1.1/USB2.0ESD防护设计推荐选型如下,为littelfuse(力特)保护器件::USB3.0 ESD防护设计推荐选型如下,为littelfuse(力特)保护器件::
