Hi Eric,

I have one more question about original thread. Customer is trying to change the value of R4 and R5 resistors.(R4: 3kohm to 4.7kohm, R5: 33kohm to 47kohm) Are there any issues on WAKE function? Please check it and let me know.

Jeffrey,

The calculation the resistor network for the WAKE pin is described in the datasheet. Please let the customer know to use this section of the datasheet to calculate these values.

Jeffrey,

My mistake, it is not included in the datasheet. On our other transceivers with WAKE, the explanation is as follows:

Please let us know if there are any other questions.

Jeffrey,

That is taken from the TCAN1043A-Q1 datasheet, but the concept is the same. The TLIN1021A-Q1 is the only single-channel LIN transceiver with WAKE that we have in our portfolio.
