TUSB4041 refer design request

Liu Dong

Hello ,

could you help to supply me the TUSB4041 Refer design without EEPROM , I have checked the datasheet of the TUSB4041, but there are not detail for No EEPROM application , we don't know how to use some of the PIN s without EEPROM situation .

we have doubt of those PINs , PIN1, 3,4,5,6,7,8,9,10,11, 12, 13,14, 15, 64, if don't use external EEPROM , whether make those PINs unconnected, thanks .

Hello,
I need to know which setting do you need on your implementation, for example:
Pin 1, do you need battery charging support? Are you implementing external power switches?
Depending on your requirements is the setting you have to use, all the internal PU/PD are active all the time so you can leave them floating if you are not using the features.

Hello,

Our design no need battery charging function and power switching function , we will use 5V voltage to every VBUS directly , so whether we can leave PIN1, 3,4,5,6,7,8,9,10,11, 12, 13,14, 15, 64 unconnected ? Or you can tell me how to use those pins in my request, thanks.
