BQ27530-G1: Values for Temp Model parameters in Data Memory

Part Number: BQ27530-G1

Hi everyone,

I want to configure the fuel gauge to measure temperature using the NTC thermistor installed on a Varta LPP 503759 8HH battery. As I understand, for a more precise mesurements, I need to configure Temp Model parameters, like Ext a Coef N, Ext type1/2 Coef N, Ext Min AD and Ext Max Temp. So far, I've found this thread:

e2e.ti.com/.../868181

with a link to the excel document that can calculate five Ext a Coef N parameters, Ext Min AD and Ext Max Temp parameters. However, it's still not clear how to obtain Ext type1/2 Coef N parameters of the Data Memory. Are they simply B coefficients from this excel doc? Also, should I change any Int... parameters, or do they refer to the internal fuel gauge temperature sensor and I shouldn't change them at all?

Regards,

Pavels
