Tool/software:

Hi team,

I'd like to block the power from PMID to VBUS in OTG mode.

Is there any possible way by software?

Best regards,

Hi Woosik,

During OTG mode in BQ25638, there's no way to shut off RBFET selectively.

May I ask which end application/use case are you considering?

Thanks,

Shuvam

Hi Shuvam,

I am trying to replace BQ25895 which VBUS pin is an input and PMID is a boost output.

Thanks,

Best regards,

Woosik Lee
