When I connect the input power source and the 2 cells battery the circuit does not work, i think that QBLK is continuously triggered, here voltage waveform at PMID pin; voltage at VBUS is 5V constant
Here my schematic as reference:

Hello,
If the input voltage is not getting above 4.0 V you could be failing poor source detection. Does this waveform happen seven times and then stop until POR and it does it again?
