Inquiry about temperature calculation method using bq76940 evaluation software

Other Parts Discussed in Thread: BQ76940,

Hi

I have a question about converting the temperature data to the actual temperature when checking the data using i2c communication with the bq76930 chip using the bq76940 evaluation software.

Please tell me how to derive the data “0x1085 Vtsx” displayed on Temp Sensor 2 in the current window among the attached picture files as the actual temperature using a calculation formula.

"VTSX = (ADC in Decimal) x 382 µV/LSB (4)

 RTS = (10,000 × VTSX) ÷ (3.3 – VTSX)"

If you look at the menu, it says to use the above formula, but I don't know how to calculate it in detail.

NOTE: The thermistor resistor value is 10K Ohm

Please...
