具有局部联网睡眠模式的TJA1446 CAN FD收发器属于TJA144x收发器系列，该系列实现了ISO11898-2:2024参数集A-B中定义的CAN FD。TJA1446可与高速经典CAN和CAN FD协议完全互操作，并经过充分开发和认证，符合ISO26262 ASIL-B标准。

TJA1446通过ISO11898-2:2024中规定的选择性唤醒功能支持CAN局部联网，即使在CAN总线流量运行时，收发器也能保持在睡眠模式，无需处于活动状态。

TJA1446在TJA1445的基础上扩展了功能集，包括两个可配置的GPIO引脚、一个带有专用复位和故障安全/跛行回家引脚的问答看门狗，以及精确的VIO欠压和过压监测。

TJA1446提供CAN FD/CAN XL无源功能，在睡眠模式下，该功能可防止收发器被唤醒，并在进行混合总线通信时保护CAN控制器免受CAN FD和CAN XL消息的干扰。
