ISO1042: CAN bus wake up with isolated CAN transceiver

Part Number: ISO1042
Other Parts Discussed in Thread: ISO6741, TCAN1043

Dear All,

I am looking for a isolated CAN transceiver for my application which provides a indication of CAN bus activity. This indication to be used to wake up the system from sleep state. I went through many isolated CAN transceiver but there is no specific information or parts available on how the CAN transceiver wake up on the bus activity and intern wakes up the system ( lets say a PMIC with CANWU input wakes up the entire system)

One solution which I am familiar with is to use CAN transceiver with INH pin with digital isolator to isolate TX and RX pins.

Need suggestion on this regards if there could be a better and cheaper solution available with TI

Looking forward to hear from you soon. Wishing everyone happy Christmas and New Year 2021.
