BQ24735: After adapter plugging in about 4 seconds, charger disable charging.

Part Number: BQ24735

Hello Sir:

We are using BQ24735 on our tablet, but we have an issue that after adapter plugging in about 4 seconds, charger disable charging.

Please refer our waveform and schematic as below figure.

And we also check charge options register, that bit 0 is 0, bit 4 is 1 and bit 6 is 0.

We cannot find out the problem.

Please help to provide your recommendations for us.

Thanks a lot.
