TCAN1145-Q1: TCAN1145-Q1 Application Problem

Part Number: TCAN1145-Q1

Tool/software:

Hi,

When the TCAN1145-Q1 transceiver is enabled with selective wake-up function, the following scenario is encountered: the bus periodically sends wake-up messages, first wakes up the device normally, and then disconnects one of the CAN lines (CAN high or CAN low) on the device side, the device goes into sleep mode, and then the disconnected wire is correctly connected back. At this time, the device receives a wake-up message and cannot wake up normally. The customer expects the device to wake up normally after reconnecting the wire. Is this a device characteristic of the transceiver? Or is there a problem with the mode configuration of the transceiver? Or other questions?
