Hello team,

I received a question from the customer.

If only VIO is shut off from VCC (5V) and VIO (3.3V) being supplied, does VCC ever affect the VIO line?

Regards,

Masa

Masa,

No, but the device will go into protected mode if VIO is not supplied, disabling any CAN communication function. VIO only affects the logic pins (TXD, RXD, STB) of the device, and VCC affects everything else, including the reference for the CAN bus bias.

Please let us know if you have any other questions.

Regards,

Eric Hackett
