BQ25618: VBP Control while Charging

Hi Ning,

After further investigation, we can not turn off BST_CONFIG while USB is inserted. Is there a way to set BST_CONFIG 0 while USB is inserted?

Thank you,

Ambroise

Ambroise,

Could you please provide the charging operating conditions such as VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS and all the register readings before the VBUS USB is inserted?

Thanks,

Ning.

HI Ning, the satus is as follows:

Vbus: 0V

Ibus: 0mA

Vbat: 3.565V

Ibat: 0mA

Vsys: 3.565V

Isys: 0mA

Best regards,
Ambroise

Ambroise,

Could you please also provide the charger operating conditions such as VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS and all the register readings after the VBUS is inserted?

Thanks,

Ning.

Hi Ning, 

Following the data after VBUS is plugged in:

Vbus: 5.13

Ibus: 151mA

Vbat: 3.593V

Ibat: 198mA

Vsys: 3.63V

Isys: 0mA

Best regards,
