The IC BQ24035 is powered by AC adapter of 5V, but the OUT (pin 15,16,17) is same voltage with input voltage. Seems it is internal Q2 is closed so that the charger IC cannot charge the battery. Please give me the suggestion.

Hi,
ARe you able to provide a schematic? Was the device charging previously?
Can you provide a voltage waveforms for the ISET1 pin, BAT pin, and OUT pin when the device is turned on and about 100 ms after that?
Best Regards,
