Could anyone please help in this case? It is found that the voltage waveform of the SYS pin of the BQ is abnormal sometimes when the battery is not connected and the USB power supply is inserted, as shown bellow? What might cause this?
And what will happen if the bit EN_NOBATOP stays 0 , and the battery is not connected?(We can see from the datasheet: 0-Normal Operation;
1-Enables No Battery Operation when termination is disabled (default 0))
