Hi Team,
Could you please help check why there is VIN falling time difference, which will cause the ACOK drop delay. I am checking with customer about the Host control logic when removing the adapter, at the same time need check with BU about any advice.
Failed case:
Pass case:

Hi Tiger,
They find the charger will auto set the 0x3D to 3AC0.
Is it because our offset voltage is 1.28V below the no load VBUS voltage? If the adapter is removed, shall we consider DC offset 3.2V?
Best Regards,

Hi Tiger,
The register settings of PASS and FAIL are shown in the attachment;
Disconnect the EC:
Disconnect EC-charge and then plug in the adapter. The automatically updated value of the 0X3D register is consistent with the value under FAIL, which is '3AC0'.
May I ask what is the logic for updating the 0X3D register of your BQ25700, BQ25710, BQ25720, and whether the update time is fixed?
Best Regards,
Jaden Yue
