Hello, I have a project that uses LTC1760 to charge, the fuel gauge is BQ40Z50R1, I would like to inquire whether the pull-up level can use 3.3V pull-up. Also, the low level of the LTC1760 is 0.8V. Will it be risky to pull it too low?

Hi apaqi0,
If you are referring to the logic levels found on page 6, it says 2.1V is the minimum for logic high. I think pulling it up to 3.3V is okay since the abs. max is 7V. Similarly, 0.8V for logic low is the maximum which most likely means you can pull it lower 0.8V.
