【应用】纳芯微双通道数字隔离器NSI8221N1-Q1SPR用于BMS,数据传输速率高达100Mbps
标准中定义中BMS包括控制板与采集板,其控制板与采集板之间是需要通信进行数据交换,BMS上有低压电路,也有高压电路,因此在高低压之间则需要使用通信隔离芯片。本文介绍纳芯微双通道数字隔离器NSI8221N1-Q1SPR在BMS应用上的优势。
NSI8221N1-Q1SPR典型应用电路如下:
图1 NSI8221N1-Q1SPR典型应用电路
NSI8221N1-Q1SPR功能逻辑框图如下:
图2 NSI8221N1-Q1SPR功能逻辑框图
如图2所示,NSI8221N1-Q1SPR基于容性隔离屏障技术,数字信号通过发射端内部振荡器产生的射频载波调制,通过容性隔离屏障在接收端解调。该调制采用OOK调制技术,具有高抗噪性和低辐射电磁干扰的优点。
NSI8221N1-Q1SPR主要参数特性:
表1 NSI8221N1-Q1SPR主要参数
由上可知,NSI8221N1-Q1SPR工作电压范围2.5~5.5V,可覆盖大多数主控器件供电范围,供电方案更简单;共模瞬变抗扰度CMTI可达150kV/μs ,可避免高噪声瞬变导致失去信号的完整;传输速率高达100Mbps, 传播延迟小于15ns,高传输速率和极低的传播延迟可保证信号传输过程中的稳定性和及时性;工作稳定范围-40℃~125℃,满足车规级AEC-Q100认证。
综上所述,BMS的通信隔离方案选择纳芯微双通道数字隔离器NSI8221N1-Q1SPR十分适用。

【选型】国产双通道数字隔离器NSI8121N1Q与ADI的ADUM1201ARZ-RL7参数性能对比分析
为了防止各模块之间因为压差及电流差值过大造成相互影响,一般通信接口会使用隔离器件进行信号电平转换。隔离方式会有容隔、磁隔及光隔。现介绍一款纳芯微电子的双通道数字隔离器NSI8121N1Q,其功能与ADI的磁性隔离芯片ADUM1201ARZ-RL7较相似。
