malugu Posted November 15, 2019 Report Share Posted November 15, 2019 In the test BQ76PL536PAPT sampling process, it is found that when a channel inputs a signal with periodic interference, the BQ sampling is abnormal. We superimpose a 1KHz peak-to-peak 5V square wave into the BQ sampling circuit, which will act on the CELL2 channel equalization MOS tube to achieve periodic changes in the input voltage. Finally, a triangular wave with a period of about 17s is obtained. I don't know where the problem is. Quote Link to comment Share on other sites More sharing options...
