want to make bq24192 to charge at Host mode instead of powering the device connected

Other Parts Discussed in Thread: BQ24192

Hello,

      we want to make the  intel casper tablet to charge in HOST mode without giving power to devices connected to the externally powerd hub.

 for that we have disabled the boost mode in the driver ,so now it not suppliying power outside . but in our case it should charge now .

I have tried with driver code to make it charging (bits 4:5  - 01) in REG 01  but i cant get the required result.

we are having doubt whether it  can be done through software itself or we should do something in hardware ???

Please give a solution as soon as possible ........Thank you in advance

  • Hi,

     

    I'm not sure I understand your question. The bq24192 can either charge the battery (REG01[4:5] = 01) when the adapter is connected, OR can provide power from the battery via Boost Mode when the adapter is not present. 

    In your system, where is the "externally powered hub" you're referring to connected?

     

    Best Regards,
