TJA1145A : availability of RXD pin resume signal for CAN selective wake-up

[ec23930]

Hi,

I have a question about TJA1145A CAN transceiver.

As described in the datasheet section "7.2.2 CAN standard wake-up (partial networking not enabled)", the RXD pin will be driven low after the chip has detected a valid standard wake-up pattern at Standby/Sleep mode.

If the chip has been properly configured for CAN selective wake-up in CAN partial networking function, does the RXD pin still would be driven low after it has detected the valid selective CAN wake-up frame when entered the sleep mode?

Thanks.

Hi Ernest,

Yes, when you configure the TJA1145A for CAN selective wake-up in partial networking mode, the RXD pin will be driven low after detecting a valid CAN wake-up frame.
