Dear Texas Instruments Support Team,
I hope you are doing well.
Approximately four months ago, I contacted your team regarding the charging system for my project. I am now continuing development of a USB Type-C power system using components originally recommended by your support team.
The intended device set was BQ25970, TUSB422, and MSP430. However, after reviewing the available information, I was unable to find enough documentation for BQ25970, and I was also unable to obtain the datasheet. For that reason, I have replaced it with BQ25968, which I understand to be functionally similar for my application.
I would appreciate your confirmation on whether this substitution is appropriate for the intended design.
In addition, I have a few questions regarding the TUSB422 device:
Can 3.3 V be used for the pull-up resistors instead of 1.8 V, or is 1.8 V strictly required for proper operation?
I have not been able to determine the correct connection method for the INT_N pin. Could you please advise the recommended implementation? Additionally, what would be the effect of leaving this pin floating?
Thank you for your time and support. I look forward to your response.
Best regards,
Georgi Georgiev
