Other Parts Discussed in Thread: BQ27Z561
Dear team, I have encountered a problem with the current accuracy of BQ27z561, specifically: the customer has designed two versions of PCB, the RSOC accuracy error of the second version is obviously larger than that of the first version.Already calibrated with GRCRB tool.The blue box in the picture above shows the current sampling module designed by the customer, and the green box in the picture below shows the running method of the current sampling line. Please check if there is any problem?And now I also want to check whether it is a PCB problem, and you need to provide BQ27Z561EVM -011 PCB design drawing for comparison, thank you for your help!
