BQ25303J: Battery Charger + Fuel Gauge

Hi Aviv, 

Thank you for reaching out via E2E. Firstly, if you are looking for fastest possible support I recommend you create alternate E2E forum posts requesting schematic reviews for the specific parts in question. This will allow all the appropriate device experts to review the relevant portions of the schematic in parallel. 

I have reviewed the BQ25303J portion of the schematic, and see no clear issues. Required component connections are present. I have also transferred this thread to have other 'BQ' parts (i.e. fuel guage and protector) reviewed by appropriate experts. 

Best Regards,

Garrett

Where is the actual cell connected in your schematics? The charging current and discharging current must both flow through the sense resistor. I cannot identify the current path from your system through the gauge to the cell in your schematics. Please elaborate.

Hi Garrett,

I appreciate your review.

Thank you,

Aviv

Hi Dominik,

Attached here is the updated schematic with a clear connection of the battery position.

Let me know if a correction is needed.

Thank you,

Aviv
