Other Parts Discussed in Thread: BQ24392

Dear Sir:

Please advise what the switch status (the detection table on page 8.) connected or not connected will be ?

The circuit is CPU <=> BQ24392 <=> USB connector,
Condition : To connect the device with ID pin low to USB connector, we support OTG function for this

Please tell us the result will be “connected” or “not connected”

Thanks!

    Hello Milk Wang,

    Please help me understand the question better.

    Are you saying that you have another device that will detect the ID Resistance of <10 Ohms on the ID Pin and signal that an OTG device has been connected?

    If so, then I am assuming your battery charger will provide power to the Accessory, resulting in >3.5V present at VBUS.

    If both of the above are true statements, can you tell me what D+ and D- will be attached to in the accessory? Will they be floating?

    Regards,

    Brian
