Part Number: TPS25830A-Q1

Dear expert,

Customer is using TPS25830A for a type-A USB charging.

Can they simply configure CTRL1 , CTRL2 to 1, 1 and then TPS25830A can drive 2.1A to mobile?

Thanks

Ziv,

From the description, it seems 3A is only supported by type-C for CTRL1,2 set to 1,1? For type-A, it is only 1.5A for CTRL1,2 set to 1,1?

But it also mentioned "Current Limit Setting using RILIMIT". Can I set current limit as 3A with Rilimit to enalbe 3A for type A?

Thanks

Ziv,

BTW, customer wants to support 2.1A charging current while USB type A data communication is still normal.

So they can only choose SDP mode but not CDP mode?

Anyway , need you suggest the best way for them to support USB type A 2.1A charging capacity with data communication ongoing.

Thanks

Hi Ryan,

I think it's for apple divider mode.

Can't support 2.1A for type-A with data communication normal.

Ziv,

So for data communication normal, they have to choose SDP, right?

So max current is 1.5A for type A+SDP, right?

Ziv,

Thanks. So CDP+type A for 1.5A max, right?
