Excuse me. Based on what information does the current charging status of the charging chip (REG0x21--[2:0]) change automatically? If it is judged according to the current battery voltage, when there is no input current at this time, the indication of this register is wrong, because the chip is not charging at all. Just like the project I'm working on now, a solar panel is used as the input source of the chip. When the sunlight is poor, there is an input voltage but no charging current. At this time, the status I read from the register REG21 is fast charging, which greatly affects my judgment of the current charging status. Are there any good methods that can help me better judge the current charging status?
