在本地互联网络(LIN)中,TJA1021是LIN主/从协议控制器和物理总线之间的接口。主要用在使用1 kBd至20 kBd波特率的车内子网络,符合LIN 2.1/SAE J2602。TJA1021与TJA1020引脚对引脚兼容,静电放电(ESD)规格有改善。
通过TJA1021将发送数据输入(TXD)的协议控制器发送数据流转换成具有最佳转换率和波形整形的总线信号,以使电磁辐射(EME)最小化。LIN总线输出引脚通过内部终端电阻拉高。对于主应用,应在引脚INH或引脚VBAT和引脚LIN之间连接一个与二极管串联的外部电阻。接收器会检测LIN总线输入引脚的数据流并通过引脚RXD将其传送至微控制器。
在睡眠模式中,TJA1021的功耗非常低。在故障模式中,功耗降到最低。
