Hi, TI support team
My customer asked product that is possible for current control thru CC1, CC2.
TI product is TUSB320.
Operating senario that he want to design is below.
- USB A(Adaptor) to USB type-C(Device) : Charging under 2.0A
- USB type-C(Adaptor) to USB type-C(Device) : Charging 3.0A
When using CC control, is it possible to control to change only the current?
Do I need to change the voltage through CC control?
Charger is a product that has an input range of 13V.
From what I've searched, it seems that the TUSB320 product is possible, but if there is a suitable product, please recommend it.
Thanks.
Regards,
MJ
Hi MJ,
The TUSB320 can set the current mode through CC1/2 with options for 900mA, 1.5A, and 3A. This would only change the current, and not the voltage on VBUS.
A CC controller like the 320 is a simple device that can only support 5V on the type-C VBUS. If you need a higher voltage, I can refer you to the PD controller team.
Just to clarify, are you making a device with a type-C port that receives power from a type-C charger as in the diagram below?
Best,
Shane
