https://devzone.nordicsemi.com/f/nordic-q-a/110695/npm1100-charging-issueWe found one charging issue on nPM1100, after we assemble the battery to the PCBA, and then apply 5V to nPM110 (VBUS) and GND. The protection ciruit does not release, and I found the VBAT output is only 1.45V (the battery voltage is around 4.15V) .
