【选型】电动汽车BMS系统SPI总线隔离选择四通道数字隔离芯片SI8641ED-B-ISR，可替代ISO7341-Q1
电动汽车BMS系统，一般会选用SPI总线主从控制模式的数据信号通讯，特点是全双工，支持多个从机，但只能有一个主机，典型SPI总线通信示意图参考如下图1所示。
图1：典型SPI总线主从控制通信模式示意图
为保证主板与从板间SPI总线通信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，一般需要一款数字通信隔离芯片对SPI总线和控制电路进行电气隔离，针对SPI总线隔离芯片选型一款考虑如下因素：
1、 四通道通信隔离，对应CLK（串行时钟）、MOSI（主出从入数据线）、MISO（主入从出数据线）、SS（片选，低电平有效）等。
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
针对如上的设计需求，推荐选择SILICON LABS（芯科）四通道数字通信隔离芯片SI8641ED-B-ISR，非常适用于SPI总线隔离设计，采用宽体SOIC-16封装，主要隔离介质是SiO2，绝缘耐压能力达5.0kVrms，电源工作温度范围-40℃~125℃，推荐理由如下：
1、 5.0kVrms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，可pin-pin兼容TI公司的ISO7341-Q1，内部功能框图和pin脚定义对比参考如下图2所示。
图2：四通道数字通信隔离芯片SI8641ED-B-ISR和ISO7341-Q1内部功能框图和pin脚定义对比示意图
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】隔离芯片SI8641ED-B-IS在电池检测设备SPI通讯隔离上的应用
2019-12-03 - 应用方案 目前的电池检测设备涉及到主从之间的信号隔离，往往会用到SPI的通讯协议，另外从安全的角度，在主从芯片之间会加隔离芯片，确保强弱电之间的隔开，保证系统的可靠性。从控制方面，希望隔离信号的延时时间低，速率相对高，所以需要高速的隔离芯片来做设计。Silicon Labs推出的SI8641ED-B-IS可以满足电池检测设备SPI通讯隔离需求，性价比高。
【应用】效率达到98.7%的低成本12KW组串式光伏逆变器
2019-08-30 - 方案 本方案源于知名企业的光伏逆变器成功案例，选取高性价比、库存充足、供货稳定的升压电路和逆变电路的功率模块，以及对应的驱动产品，可以保证12kW组串式光伏逆变器的整体功率转换效率达到98.7%。
