Hi sir
How did we Setting TUSB8040A1 to support CDP mode?
I have setting PWRONxZ_BATENx pull high and GanGED_SMBA2 pull high by HW. but Sony Xperia S get 480mA charger current.
I have use TPS2546 setting to CDP mode and use same cable and same device . Sony Xperia S can get 1.1A
How did we Setting TUSB8040A1 to support CDP mode?
Another question :
When DCP mode change to CDP mode or CDP mode change to DCP mode ( S0 to S5 or S5 to S0) the output 5V will be discharge ( 5V --> 0V --> 5V ) . This dischatge is Must be performed for TPS2546.
How to do this discharge by TUSB8040A1 or TUSB8041?
PS : output discharge ==> TPS2546 spec page 13 figure 26
