TCAN4551-Q1: Is it possible to use an external isolated CAN-driver with this controller

Part Number: TCAN4551-Q1

Tool/software:

Hi, TCAN4551-Q1 seems to be right on the project requirements, except that the CAN-driver is not isolated.

The data sheet describes a test mode where the built-in CAN-drivers are by-passed and the CAN-controller RX and TX are present at the GPIO-pins.

Is it possible/advisable to use this test mode to operate the CAN-controller together with an external isolated CAN-driver?

Best Regards,

Joakim Langlet
