Configuring a BQ34Z100-G1 directly through I2C

Other Parts Discussed in Thread: BQ34Z100-G1, BQ34Z100, BQSTUDIO

Dear TI,

I have a BQ34Z100-G1 IC connected on my own PCB design, and I'd like to set some configurations and calibrations in the IC through I2C. The user guides mention how to do this with BQ34Z100-G1-EVM and the EV2300 module through the Battery Management Studio GUI. However, I would like to configure the BQ34Z100-G1 IC on my board directly through the EV2300 and Battery Management Studio. 

I have I2C pins available to directly connect to the BQ34Z100-G1 IC from any external source (like the EV2300), so that shouldn't pose a problem. And if I would like to automate the configuration of this IC, could I do that with a simple script which is run from anything like an MCU, Raspberry Pi, Arduino, etc.?

Kind regards,
Javier

    Dear TI,

    From my last post on May 25 I have not received an answer as yet.
    This information is important to help out with my development/production.

    Can you please assist me in knowing the answers to my questions?
    Thank you very much in advance.

    Kind Regards,
    Javier

    Hi Javier,

    First of all, I would like to apologize for taking so long to respond to your question. It is possible to configure the BQ34Z100 on your PCB board using I2C and the EV2300. However, to use bqStudio with the gauge on your PCB, the I2C bus must be idle (ie idle microprocessor) and the voltage levels must be compatible. You can find information about the voltage levels in the data sheet.
