Part Number: BQ40Z60
Tool/software: Code Composer Studio
Hi Onyx:
1, I notice that default thermal coefficient table is like below after I programming 'bq40z60_v0_15_build_21.srec'(default FW for BQ40Z60) into BQ40Z60? So I want to know which type NTC is compatible to below default thermal coef? In other words, what NTC does below default thermal coef get from?
| Calibration | Cell Temperature Model | Coeff a1 | -11130 |
| Calibration | Cell Temperature Model | Coeff a2 | 19142 |
| Calibration | Cell Temperature Model | Coeff a3 | -19262 |
| Calibration | Cell Temperature Model | Coeff a4 | 28203 |
| Calibration | Cell Temperature Model | Coeff a5 | 892 |
| Calibration | Cell Temperature Model | Coeff b1 | 328 |
| Calibration | Cell Temperature Model | Coeff b2 | -605 |
| Calibration | Cell Temperature Model | Coeff b3 | -2443 |
| Calibration | Cell Temperature Model | Coeff b4 | 4696 |
| Calibration | Cell Temperature Model | Rc0 | 11703 |
| Calibration | Cell Temperature Model | Adc0 | 11703 |
| Calibration | Cell Temperature Model | Rpad | 0 |
| Calibration | Cell Temperature Model | Rint | 0 |
2, I also notice BQ40Z60 datasheet recommends AT103-2. Suppose AT103-2 is default NTC, Why is thermal coef result using your excel not same with default thermal coef table?
Thanks!
