Other Parts Discussed in Thread: BQ20Z80, BQ20Z80-V102, BQEVSW, BQ40Z50-R1
Hi,
A couple of years ago I developed a battery testing system using bq20z80. My customer is still using it but has problems replacing failing BQ20z80EVM board. I am investigating a possibility of replacing bq20z80-V102 with V110. My customer has tried that and says that the system does not work. The normal process of charging and measuring charge currents does not happen. I am suspecting that a parameter change between V102 and V100 can be causing this but I do not have enough experience to troubleshoot this. There might also be another problem related to that change, I am not sure.
Also the software (bqEVSW) does not support V110 ( using 0.9.24 ). We were using it to download a set of required parameters into the board and for current and voltage calibration. Is there a way around it?
Any feedback will be appreciated.
Thanks
Jerry
