BQ25895: Can BQ25895 retry host detection?

Part Number: BQ25895

Hi TI experts,

When connecting the USB cable slowly, BQ25895 0x0B register (VBUS Status) recognizes as Unknown Charger.

We want to detect the charging type again without removing the charger if it is recognized as an unknown charger.

Is there any possible way?

Thanks,

Downey Kim.

    Downey,

    Referring to 8.2.3.3.2 Force Input Current Limit Detection on the d/s, In host mode, the host can force the device to run by setting FORCE_DPDM bit (REG02[1]). After the detection is completed, FORCE_DPDM bit returns to 0 by itself and Input Result is updated.

    Thanks,

    Ning.
