【成功案例】贴装TVS SP0505在RJ45以太网接口防护电路的应用,节约印制板空间
sp0505是LITTELFUSE公司提供一款用于ESD防护的贴装TVS(Transient Voltage Suppressor)阵列器件,满足国际静电放电实验标准IEC61000-4-2。用于保护直流5V电压以内的敏感数字和模拟输入输出电路。SP0505提供SOT23-6封装,有着极低寄生电容和钳位电压,内部集成5个TVS管,是理想的高速信号线保护器件,同时对PCB空间的影响极小,一个常见的应用场景是应用在以太网口的保护上,对于带网口产品通过EMC(Electro Magnetic Compatibility)实验和认证有非常重要的意义。下面本文就对SP0505在以太网口中应用中可能碰到问题进行讨论。
图 1 SP0505在以太网口中的应用
在以太网口连接时可按图1所示方法接入SP0505,通过这种方式将器件内部两个方向的TVS管进行串联,从而实现两极保护,在信号发送线和接收线上 无论正向过压还是负向过压可以纳秒级速度快速反应。
对于TVS管阵列的应用,最高反相截止电压应高于信号正常工作时的差分电平。根据IEEE(Institute of Electrical and Electronics Engineers)规范,百兆网口差分对信号的最高摆幅为1.05V。查询SP0505的反相截至电压最高值为5.5V,通过串联的方式可以做到更高,因此这一点是完全满足的。
在以太网口中的应用中,信号的速度越快,工作的电压越低,但是电流却更高。因此引入TVS管阵列还应注意反相截止电流不能影响信号,SP0505的反相截至电流在5V测试条件下最大为100nA,典型值为1nA,但是对于网口信号差分电压摆幅为1.05V,且采用并联方式,其反相截止电流更低,这样的能量不足以对信号质量造成影响。此外,峰值电流也是SP0505中值得注意的参数。
值得注意的是,当前的以太网口遵照10/100 Base的标准,通过的信号理论值可达100Mbit/s,属于高速信号,在做ESD防护要求不影响信号线的信号质量。因此在做防护时,需要考虑TVS管的寄生电容,特别是百兆网口工作时,阵列的寄生电容参数将对信号眼图产生影响。由于容性的存在,眼图的边缘速率将会降低,网口的回损参数也将受到影响。
通过查询手册可以知道SP0505的寄生电容参数为30pF,按照图中的器件连接方法可以近似理解对于差分线上而言寄生电容为15pF,寄生电容值极低,笔者以一款厂家的RJ45以太网接口按照图示方法应用在80MHz物理频率下,回损为-10dB,数据通信正常,选用物料号是SP0505BAHT。
图 2 印制板中TVS阵列的不合理布局
此外,在元器件布局上,SP0505BAHT的放置也要注意,其应布置在PHY芯片和变压器之前,紧挨着网络口。比如在图2中,由于需要布置多个网口,且同时需要考虑平面分割,忽视了ESD防护器件应靠近网口布置的原则,将TVS阵列放置在较远位置,造成在静电放电实验中无法通过,网口受到冲击后无法正常工作。具体而言,这种现象的成因是多种原因造成的,但是过长的TVS管布线会引入不合理的等效电感,对于百兆信号来说这是极其敏感的,极易造成回损,影响信号质量,在有干扰的情况将更加严重。因此除了尽可能近地放置SP0505BAHT,还应在信号线上连接电感电容调节回损,提高眼图效果,建议按照图3布局。
图 3 SP0505在以太网中的推荐布局
因此,从上述关于SP0505BAHT这个TVS管阵列器件在以太网接口电路中的应用中可以发现,虽然这种阵列器件可以帮助设计者节约印制板空间,提高产品ESD防护性能,但是我们还是需要结合以太网这种高速电路的本质考虑器件的选型和空间的布置。在实际设计中,除了需要参考手册和仿真设计外,更多还是要通过测试的手段即时发现问题,选择相适应的电路和器件来解决具体问题。

【经验】DCDC芯片SGM41280在电池插拔时的损坏原因分析及问题解决方案
在某客户的IoT温湿度记录仪产品的2G模块供电中使用了圣邦微的SGM41280,在调试过程中出现电池插拔之后SGM41280损坏情况,分析测试发现在电池插拔过程中SGM41280的输入端有出现8V的左右的尖峰电压,而该芯片的输入耐压值为6V Max,所以初步判定为输入电压过高导致的损坏。由于尖峰电压的能量不大,解决办法是在电源接口处增加TVS即可。推荐力特的SMAJ系列400W表面贴装型TVS。
