BQ25601: I2C data

Part Number: BQ25601
Other Parts Discussed in Thread: INA3221, EV2400

Hello,

It seems as if the part is only outputting 0's on the I2C registers. I'm able to initiate transfers, and I have an INA3221 on the same bus that I'm able to extract data from, so I'm wondering if there's some kind of initialization scheme I may be missing.

Thanks!

    Hello Nick,

    Do you have an EV2400 to test with to confirm with the TI toolchain that it is working properly? Sometimes with custom drivers there is a software bug.

    Or do you have logic analyzer and scope captures of the communication? You should be able to communicate with the charger once it has power supplied on VBUS or VBAT.

    Sincerely,
