Hi team,
My customer wants to know if they can left the GND pin of TCAN1042 floated, while only CAN_H and CAN_L are linked out to the bus, as shown in the following figure,
The isolated power is powering TCAN1042 via Vcc and STB, they want to remove the 0ohm resistor linked with isolated GND. The only CANH and CANL will be linked outside. They need this kind of process to be compatible with other products. For this case, can you advise whether there is any risk and what other things they can do (optimize layout, etc) to ensure the performance?
Regards,
Xiaoying
