TCAN1146-Q1: ACK message

Jeff Yun

Part Number: TCAN1146-Q1

Hi, Team

My customer is using our TCAN1146-Q1, and the engineer has a question:

After the customer engineer sends a wake up message, what is the process and logic for TCAN1146 to send an ack?

The customer engineer is currently finding that if canoe does not self-ack and sends a packet directly, the TCAN1146 will not issue an ack, resulting in the busoff environment no longer working.

Thank you for your support and look forward to your reply!

    Jeff,

    When the TCAN1146-Q1 wakes up, it will transition into Standby mode and notify the controller through the RXD pin. Once the device is then transitioned into Normal mode, it will be able to ACK messages it receives from the CANoe module.

    Regards,
