MAX17300 communication board?

Hello, The EVKIT can be used by connecting the J3 header SCL/SDA/GND lines from the EVKIT to your test board.

The EVKIT GUI and hardware is not ideal for production as it requires a lot of manual clicking.  We normally recommend incorporating the loading of the INI values into the production testing.  Typically a production tester already had a I2C master available for testing the IC, so the INI can be loaded with that same master following the guidance in pdfserv.maximintegrated.com/.../AN6945.pdf

Thank you for your reply, we will use the EVB jumper method to make it first

I have a follow-on question...

If header J3 of the EVKIT is used to connect to a fuel gauge on another test board, how will the MAX17300 that's currently on the EVKIT interfere with the I2C communication?  If the MAX17300 is unpowered by leaving BATTP, BATTN terminals disconnected, is that enough to prevent I2C communication problems with another test board? 

Correct, if the onboard MAX17300 is not powered, it will not communicate at all, so it will not interfere with the communication to the external MAX17300.
