TCAN1145-Q1: 如何关闭唤醒功能

Part Number: TCAN1145-Q1
Other Parts Discussed in Thread: TCAN1051-Q1,

Hi expert，

My customer is BTL and for some complicated reasons they want to use the TCAN1145-Q1 to run in only Normal and Silent modes. Similar to TCAN1051-Q1, it has only two modes of operation: Normal mode and Silent mode.

Of course, they only want to implement using the TCAN1145-Q1 instead of switching device for the TCAN1051-Q1.

Can this be achieved through the configuration of the registers?

BR,

    Link,

    You cannot directly disable the device from going into any of the modes in the state diagram besides Failsafe mode. Mode transition can be directly controlled through registers though, so as long as they can keep the device from going to Sleep mode, they can control the transitions to and from Normal and Silent mode.

    Do you have any other details of why this is a requirement?]

    Regards,

    Hi Eric ，

    thank you for your reply.

    BTL receives CAN communication requirements from different customers: PN wake-up, normal wake-up, no wake-up

    Therefore, they hope to achieve the above three functions on sample borad without having to manually modify sample borad.

    BR,
