We encountered one issue. The charging LED is always blinking when battery near full.
If I changed VOREG from 4.1V to 4.2V, the blinking issue is gone after few miniutes.
We have some question that list below.
1. Is it caused by VBAT have big change when charging current terminates?
2. If the 120 mV hysteresis in chapter 4.9.3.6(SWCS057H) can be programmable or not.
