【选型】为机房动力环监控系统RS485总线隔离选择通信隔离芯片SI8622EC-B-ISR，可替代TI的ISO7221

时间： 2020-03-12 来源：Silicon Labs

技术问答

机房动力设备（如供配电系统、UPS电源、防雷器、空调、消防系统、保安门禁系统等）一般通过智能数据接口（如RS232、RS485、RS422等）接入动力环境监控系统，为保证数据总线在严重干扰和其它系统级噪声存在的情况下可不间断、无差错运行，一般需要一款通信隔离芯片对总线和控制电路进行电气隔离，针对RS485总线隔离芯片选型一款考虑如下因素：

1、双通道通信隔离

2、绝缘耐压能力：建议选择至少2.5kVrms

3、高抗干扰

4、高信号传输速率

5、低功耗

6、小尺寸封装

针对如上的设计需求，推荐选择SILICON LABS（芯科科技）通信隔离芯片SI8622EC-B-ISR，是一款采用电容隔离技术的双通道通信隔离芯片，宽体SOIC-16封装，主要隔离介质是SiO2，绝缘耐压能力达3.75kVrms，宽工作电压范围2.5V~5.5V，工作温度范围-40℃~125℃，内部功能框图和pin脚定义参考如下图1所示。

图1：Silicon labs（芯科）容耦通信隔离芯片SI8622EC-B-ISR内部功能框图和pin脚定义示意图

推荐Silicon Labs这款容耦通信隔离芯片SI8622EC-B-ISR理由如下：

1、 3.75kVrms高绝缘耐压能力

2、高共模瞬态抑制CMTI：最低35kV/μs，典型值为50kV/μs。

3、高信号传输速率：高达150Mbps

4、具有超低功耗特性，当2.5V供电时，单通道100Mpbs传输，电源电流低至3.5mA；而当单通道1Mpbs传输，电源电流低至1.5mA。

5、市场上有成熟的应用，产品性能得到验证，同时，可pin-pin兼容TI公司的容耦隔离芯片ISO7221。

6、通过AEC-Q101认证。

7、世强电商平台有批量备货，可快速支持样品和量产服务。

【应用】Silicon Labs Si8600 I2C通信隔离芯片在以太网供电方案中的应用

NVR，交换机等设备，有支持POE供电。这些设备采用的PSE电源芯片，几乎都支持I2C通信接口，通过host端来实现功率管理。而host端电源和POE的48V电源之间是隔离的，因此I2C通信也需要增加隔离器。《支持8端口的单芯片以太网供电（POE）优选器件方案》采用Silicon Labs公司的POE供电芯片Si3459，以及I2C通信隔离芯片Si8600，实现更加高效稳定的以太网供电系统。
