Thank you Kuo. I was able to see the MA5889 datasheet.

I read the datasheet and it was unclear what the MA5889 device does in the system. Do you have schematic or diagram of what kind of a solution you are looking for? Are you looking for a device like TI's BQ24392?

Thank you,
Adam

Kuo,

Thank you for the diagram. The BQ24392 does not provide the function you depict in the above diagram. The BQ24392 device sits behind the usb connector and will tell the system what type of charger was inserted.

I will move this thread to the power management forum to see if they can help you with your question as I don't think you are looking for a signal switch.

Thank you,

Adam

TPS2549Q1 can support 12W charge for applications where the USB 2.0 data function is required. TPS2514A can support 12W charge handshake w/o USB 2.0 data support.
