Part Number:BQ24161
Hi team,
My customer is using our BQ24161 to charge a 2070mAh single cell battery. Please see the configuration as below.
When customer did the test, they use a multi-meter with waveform recording function to record the charge waveform as below. The waveform is basically correct but the termination current is 29.6mA which is out of the normal range(the termination current is set to 50mA and the accuracy is +-35%). As you can see, the charge current is 0.99A and charge voltage is 4.304V which are very close to the setting value. So I think the accuracy issue of termination current is not caused by the multi-meter error. We also tried another several charge cycles and this issue often occurs but with a different termination current value like 18mA, 80mA ,etc. Do you have any advice on this?
Best regards，
Wayne
