Hello,
I have trouble to communicate with BQ76920 via I2C. Im using arduino mega 2560 for communication. First time i tryed to communicate i turned off internal pull-ups of arduino but i didnt know that arduino has added external 10Kohm pull-ups on board. So it was pushing 5V via 10K external pull-ups to SDA,SCL... After that i made I2C level shifter, but when i connect arduino communication freez. SD is low and SCL is stucked on 1,2V. I messured resistance to ground SCL=150Ohm and SD=2KOhms. Do you think i lew up that I2C pins?
