Asking for the recommendation on the charger solution and design

Other Parts Discussed in Thread: BQ25606, TUSB320

Hi Team,

Customer is looking similar version to BQ25606 but with I2C. 

Customer is thinking to use TUSB320(as UFP) to detect type C host current capabilities, and use the GPIO output of TUSB to change I_CHG of the BQ25606. Do you think it is workable, because the BQ25606 will detect USB SDP (USB500) from D+/D-,limit the input to 500mA, and ignore the I_CHG.
Is it correct?

Would you please recommend the proper solution for this?
Could I2C be used to override the detection and the input current limit? Or it cannot?

 

 

 

 

 

BR,
