BQ4050: How to change the number of cells in bqstudio?

Tool/software:

Hello.

I'm checking feasibility of BQ4050 using bqstudio.

My application is for 4S1P cell configuration.

when battery simulator's output is 3.5V/cell,

why bqstudio does not show 'cell4 voltage'?

BAT pin voltage is about 13.5V, so bq4050 knows all cell's voltage is 3.5V each.

please check this.

thanks,

Hi Dongoh.

Could you send the .gg file?

Thank you,

Adam

in the .gg file, Cell 4 min voltage shows 32767mV in lifetime.

I wanna insert .jpg file to check main monitoring screen but cannot insert.

main monitoring shows cell1,2,3 are 3485mV, but cell4 is 0mV.

I found the problem.

I didn't set DA configuraiton.

Now I can check all cell's voltage.

thanks,
