BQ76930: External Temperature Accuracy Calculations

Part Number:BQ76930

Hi team,

My customer is working on temperature accuracy calculations for the BQ76930. The datasheet states the following:

and

Using the BQ78350 coefficient calculator:

His questions are:

Is R_TH =18000 calculated using the equations in the first cut and paste?
Since the accuracy of the internal 10K resistor is +3% how is that put into the calculator? Would I set tolerance to 3% for R_TH of the calculator? Is this the correct way to compensate for internal accuracies?

Can you please provide feedback?

Thanks,

Antonio
