Hello support team,
This is FAE Dave and here's the question from my customer that I need your help. Thanks!
They cannot charging with the current of 3A, the maximum is 2A now.
The detailed question is here:
According to the datasheet, is only the DCP mode able to charge with 3A?
The D+ and D- are empty, and not connecting to the USB port. The source detection is disable now, is 3A be able to charge at this condition?
The figure below are the datasheet and their register setting.
Here's the extra information:
They use Huawei P20 charger that supports 5V/2A , 5V/4.5A, .4.5V/5A output.
When they change REG01 to 0x10, it is able to charge with 2.5A.
If using DC source adapter, and voltage is adjust to 6V, it is able to charge with 3A.
Thanks for the help and look forward to your reply.
Best Regards,
Dave
