BQ25890: OTG and USB charging support

JH Shin

Part Number: BQ25890

Hello,

Does the OTG function of BQ25890 only support the OTG function when it is in High ? Or can it support OTG and USB charging together?

Thank you.

Hi JH,

The BQ25890 cannot support charging and OTG functions at the same time. The same switching FETs (Q2 and Q3) are used for buck charging and OTG boost operation, hence the IC cannot be in OTG mode while charging.

Best Regards,

Garrett
