Hello Team,

My customer is looking for some product which can do the function of both battery charger and fuel gauge on a single chip.

Do we have a solution for them

What is their application? Single-cell or multi-cell?

Hi Mayank,

BQ40z60 is the only one I can find so far. However, we don't recommend this part.

See this thread. https://e2e.ti.com/support/power-management/f/196/t/875348

I would suggest your customer use the bq40z50-R3 and a discrete charger.

Hi Mayank,

We don't have an integrated chip for both charger and fuel gauge. We recommend discrete gauge and charger. If application is up to 4 cells, please use BQ40z50-R2 orderable device, and flash the latest BQ40z50-R3 FW on that. If application is up to 7 cells, please use BQ40z80.

Please go to http://www.ti.com/power-management/battery-management/charger-ics/overview.html to help select a charger IC.

Thanks,

Rushi
