bq20z75 calibration process

Dear all,

 

I have a two questions

Question 1:

  • In the TI documentation regarding calilbration it is pointed out that only one type of calibration should be done at the time, e.g. only one box checked and alle the other unchecked.
  • What will happen if  CC offset, Voltage calibration and Temperature calibration are all checked, correct values for actual voltage and temperature is entered and the button Calibrate part as indicated below is pressed?
  • Is it likely that the quality of the calibration process will not be accurate ?

Question 2:

  • When the bq is programmed with a Golden DFI file will the data be transferred from the DF to the AFE part automatically or is it necessary to do a reset to transfer DF parameters from the data flash to the AFE like when changing DF parameters like OC, SOT etc to the AFE? 

Any comments will be very much appreciated

 

Best regards
