  • 建议不要在新设计中使用本页介绍的产品。

TJA1145是一款高速CAN收发器，可在控制器局域网(CAN)协议控制器和物理双线式CAN总线之间提供接口。该收发器专门设计用于汽车行业的高速CAN应用，可以为(微控制器中的)CAN协议控制器提供发送和接收差分信号的功能。

TJA1145在待机模式和睡眠模式下具有超低的功耗，通过使用选择性唤醒功能，支持符合ISO 11898-6:2013标准的CAN局部联网。

局部联网功能的专用实施已嵌入到TJA1145/FD产品TJA1145T/FD和TJA1145TK/FD中。此功能称为“FD-无源”，它在忽略CAN FD帧的同时可以在睡眠/待机模式下等待有效的唤醒帧。如果网络要同时支持CAN FD和标准CAN 2.0通信，那么这个新增的局部联网功能将会是很好的选择。在CAN FD通信期间，它允许无需传输CAN FD消息的普通CAN控制器继续处于局部网络睡眠/待机模式，而不产生总线错误。

高级电源管理调节通过节点的电源，并支持本地和远程唤醒功能。I/O电平会自动调整到控制器的I/O电平，使得TJA1145可以直接连接到3.3 V-5 V的微控制器。提供SPI接口用于执行收发器控制和检索状态信息。电源断开时，总线连接变成为真正的浮空连接。

TJA1145实现了当前ISO11898标准(ISO11898-2：2003，ISO11898-5：2007和ISO11898-6：2013)以及ISO 11898-2：2016即将发布的更新版本中定义的CAN物理层。包括CAN FD和SAE-J2284-4的ISO11898-2:2016版本即将发布，包含了用于定义循环延迟对称性的新增时序参数。在CAN FD快速相位下，即使数据速率高达2 Mbit/s，此实施也能实现可靠的通信。

这些特性使TJA1145成为一些高速CAN网络的很好选择，这些网络的节点一直与电池电源线保持相连，但是，为了让功耗尽可能降低，仅会在应用需要时才处于活动状态。
