【应用】5V电源下在PS/2接口避免受到ESD和过电流危害的电路保护方案
PS/2接口使用的数据信号的最大量值为5V,数据传输率为10,000 bps。 到达该数据传输率时,不需要考虑抑制器的电容量, 需保护Data和Clock信号线避免受到ESD危害,同时也需要保护5VDC电源避免受到ESD和过电流的危害。
如下图(上方)所示,可在电源总线和数据线路上使用LITTELFUSE推出的多层压敏电阻V5.5MLA0402来防止其受到ESD影响,同时还使用了自恢复PTC 1206L050,以提供自恢复过电流保护。 除以上方法外,也可使用瞬态抑制二极管SP0503BAHT防止数据线路和电源总线受到ESD影响,如下图(下方)所示,并减少产品数量。IEC 61000-4-2是最适合此接口的标准规范。 通过该测试可证明终端产品不易受到ESD危害。
PS/2接口的电路保护电路图
多层压敏电阻V5.5MLA0402采用了无引线、表面贴装技术。用于抑制各种瞬态事件,包括IEC 6100-4-2规定的或其他用于电磁兼容性(EMC)标准的瞬态事件。 它可在比齐纳二极管更广泛的温度范围下工作,并有比塑料组件布局更小的封装尺寸。而自恢复PTC 1206L050符合RoHS标准且不含铅和卤素,可为空间极为有限且需要自恢复保护的应用提供表面贴装过电流保护。
方案二中的SP0503BAHT已淘汰,可刚换为SP0503BAHTG瞬态抑制二极管阵列。SP0503BAHTG可满足国际电工兼容性(针对静电放电要求的IEC瞬态抗扰度标准61000-4-2)。 在高至5VDC电压的条件下,该系列可用于帮助保护敏感数据或者数据、信号或控制线路的模拟输入电路。 单片硅阵列有特别设计的瞬态电压抑制(TVS)结构组成 这些结构的大小和形状专为瞬态保护而定制。 低电容和箝位电压是高速信号线保护的理想之选。

【应用】离散型多层压敏电阻V9MLA0402在视频输入/输出中预防ESD侵害方案
用于超级视频和复合视频格式中的视频信号通常会在0.5至2.0Vp-p之间变化,最高频率可达5MHz。建议使用Littelfuse推出的离散型多层压敏电阻V9MLA0402进行保护。 鉴于视频信号所具有的模拟特性,不建议使用单极瞬态抑制二极管阵列,因为这样可能会切断视频信号中的负极性部分。

【应用】信号负值为-0.5V或更小时耳机采用单级瞬态抑制二极管的解决方案
此类音频线路的最大信号值可达12 Vp-p,工作频率小于30kHz。建议仅在耳机信号负值为-0.5V或更小时使用Littelfuse推出的单级瞬态抑制二极管阵列SP0502BAHTG或SP0502BAJTG,因为它们可在量值较大时削减音频信号的负值。
