Hi Junqing,

The BQ28Z610 and the BQ40Z50-R2 are two possible options for a 2S battery. Here are some links to help start learning about these devices:

Hi Junquing,
The bq28z610 and bq40z50 are going to be the best options for gauging and protection for a 2S battery pack.

I need a 2s battery charge IC deploying Narrow VDC architecture (NVDC) with BATFET separating system from battery. And there is a battery gauge for use with the 2s battery charge IC.

Hi Junquing,

The bq40z50-R2 is the correct device for this application and will work with the NVDC architecture. The bq28z610 can also work.
