Hi TI Support,
I am working with the BQ25723 for a battery charger project. The battery is a 3S LiPo and the schematic of the Battery Charger follows the main indications provided by the TI documentation.
During some charging cycles, I notice an abnormal behaviour of the charging current when the charger enters in the CV region: as can be seen from the picture below, once the converter enters in the CV region (the charging current starts to decrease) sometimes there is an unexpected current peak.
In the test case above, charging current was set to ~5A but this effect is noticed for different current values.
Moreover it can be seen that the peak is not always triggered: in case of consecutive charges, the peak is almost never triggered on the first cycle and then starts to appear for the following cycles, so I am wondering whether some thermal correlation may affect the behaviour of the BQ25723 or if the root cause is something else.
Thanks,
Regards
Alberto
