【选型】POE安防摄像机以太网I/O保护电路中的TVS选型指导

时间： 2019-06-26 来源：Central

技术问答

安防监控系统是应用光纤、同轴电缆或微波在其闭合的环路内传输视频信号，并从摄像到图像显示和记录构成独立完整的系统，能实时、形象、真实地反映被监控对象，可以在恶劣的环境下代替人工进行长时间监视，通过安防摄像机记录下来。

图1 安防摄像机实物图

POE（Power Over Ethernet）供电指的是在现有的以太网Cat.5布线基础架构，不作任何改动的情况下，为其他基于IP的终端提供传输数据与直流供电的技术布线灵活，具有无需复杂电源布线，摄像头不用接电源线等物件，网线供电，美观简洁等优势。Central Semiconductor公司能够为POE安防摄像机提供分布式半导体解决方案，最大限度地减少传输损耗，其提供的拓扑结构如图2所示，主要包括I/O Protection、uController Function、Motor Drive/Control、PoE Controller和Audio Amp五部分。

图2 POE安防摄像机拓扑结构

其中I/O Protection主要为以太网接口提供防雷击和防浪涌电压保护，两种保护电路基本原理如图3所示，当电路承受浪涌电压时，TVS会把浪涌电流泄放到大地中，实现对以太网电路的实时保护。

图3以太网接口I/O保护电路基本原理图

TVS利用器件的非线性特性将过电压钳位到一个较低的电压值实现对后级电路的保护，进行设计选择应具有以下特点：

1）首先确定被保护电路的最大直流或连续工作电压；

2）TVS的额定反向工作电压VR应大于或等于被保护电路的最大工作电压；

3）TVS的最大箝位电压VC应小于被保护电路的损坏电压；

4）TVS的最大峰值脉冲功率PW必须大于被保护电路内可能出现的峰值脉冲功率；

5）在确定了TVS的最大箝位电压后，其峰值脉冲电流应大于瞬态浪涌电流；

6）直流保护一般选用单向（UNI）TVS二极管，交流保护一般选用双向（BI）TVS二极管。

Central Semiconductor公司的TVS产品众多，性能优越，可提供单向和双向TVS产品，用户可以灵活选择在直流保护或者交流保护使用。其推荐三款TVS产品1.5SMC68CA、1SMB58CA和C4SMAFL58A实现以太网的 I/O保护，其主要电气参数如图4所示。

图4 TVS主要参数

Central Semiconductor公司的TVS产品1.5SMC68CA、1SMB58CA和C4SMAFL58A峰值功耗大，漏电流小，工作温度范围广，封装尺寸小，能够在POE安防摄像机以太网I/O保护电路中发挥关键作用。
