Part Number:ISO1042
Dear Ti Expert,
I would like to ask about ISO1042 IC applications. I have more than two devices using ISO1042.
Can I supply multiple ISO1042's VCC2 using one power supply?
I can't find information about the power supply application of VCC2 of ISO1042
You can provide more information on the power usage method of the CANBus side.
Please refer to my reference schematics.

Hello, yes, the VCC2 termination could be used one power supply only if it could supply the enough current.
In addition, all the VCC2 referred to GND2, while GND1 is for everything connected on side 1 of ISO1042. There should be no path from GND1 and GND2.
