Hi,
Accordingly to TJA1049 product datasheet rev 6 15-01-2018 CAN bus is OFF (ZERO LOAD) is when Vio is below Vuvd(VIO)
Accordingly to AH1021 rev 1.0 28-05-2010 CAN bus is OFF (ZERO LOAD) when VCC is below Vuvd(swoff)
What is the state of the CAN bus of a TJA1049T/3 when VCC is 0V and Vio is 3.3V ?

thank you,
I'm asking, because the value Vuvd(swoff) is not in the datasheet rev. 6 15-01-2018.
another question:
when the TJA1049T/3 is in standby mode (pin 8 STB is high) CAN-H, CAN-L is biased to GND instead of VCC/2.
What is the bias current / resistance ?
Thanks.

Hi,
Please see AH1021 page10 table1 for the detail.
Thanks!

Hi,
For all the bus line and CANH/L parameters you can only refer to datasheet page11 except it no more information.
