BQ76952: EV2400 with BQ7695202 over i2c (through ISO1640).

Part Number: BQ76952
Other Parts Discussed in Thread: EV2400, BQSTUDIO,

I have now got an EV2400 where i am going to use the Port 2 i2c (pins Vout, Vss, SDA and SCL.
These are going to be used instead of the raspberry pi pico w  (unplugging) for setting up and monitoring the bq7695202
But there is no power at the Vout. How can I enable it from the bqStudio?

  • Hello Steinar,

    Why do you require VOUT from the EV2400?

    You could enable the REG1 or REG2 from the BQ76952 and use that as the pull-up of the BQ76952 I2C lines.

    Now, I see you asked how to do this in a separate thread, in which the team that developed the EV2400 has answered. So they will be able to help on that regard.

  • I think I was quite clear that there are two voltage potentials, that is why i am using the iso 1640/41. And the difference Between side 1 and side 2 (already powered by reg 1) may have a potential, up to 400vrms

    So my question again, how do i enable the Vout?

  • Otherwise, the other tread does not seems to work for my part, because the instructions does not have the same instruction (maybe different sw version).
    But I just need someone from TI to help me out here. Should not take more than 10 min. for the right person. I have purchased a 100 pc. of the BQ7695202 and now also the EV2400. So I really hope someone from TI can work this out. How to enable VOUT2 ??

  • Hello Steinar,

    I understand now! So you have side 1 with the REG1 and want to use the other side to connect to the EV2400.

    I searched briefly on E2E and it seems that it is not possible to manually control the GPIO pins of the EV2400. I am not part of that team, so I do not have in-depth experience with how it works. That's why I'd suggest to follow up on the other E2E to see if it is possible to make it happen.

    Now, I am wondering, why not use a GPIO or supply from the rasp-pi board to connect to the other side of the ISO?
