Hi TQ,

Thank you for your question, but I'm not sure what part you're referring to. What's the part number of the device?

Hi Aramis-san,

I'm recogniaing it doesn't depend on device.

I would like to know specified current value by Samsung on 1.2V/1.2V mode.

2A is mentioned in the datasheet of TPS2549.

Is this specified value?

Best Regards,

Kuramochi

Hi,

1.2V/1.2V is Samsung 10W charging protocol. which means the host USB can provide maximum 2A current to the device.
