Part Number: TUSB4020BI Dear supporter,
we need to use TUSB4020BI for our design. i checked the spec of TUSB4020BIPHPR and TUSB4020BIPHPRQ1, and i did not find any difference. the work temperature is same, TUSB4020BI's ESD level seems even better. is the…
Part Number: TUSB4020BI-Q1 Hi Team,
Could you help to clarify the sequence definition of the td1 in the TUSB4020BI-Q1 datasheet?
We might facing a timing issue on the VDD33 and VDD so need to clarify the definition of td1 delay and the voltage threshold…
Part Number: TUSB4020BI-Q1 We have made 10 circuit cards, 2 of which are fully functional, and when the other 8 are connected to the computer, the computer often cannot scan and find that the TUSB4020BI-Q1 has been inserted into the USB port, and often…
Part Number: TUSB4020BI-Q1 Hi, Team
Hope you are doing well!
I have a question about the PWRCTL1/BATEN1 Pin of TUSB4020BI-Q1.
In datasheet, PWRCTL1/BATEN1 is described as I/O Pin, as input Pin, it is used for control of the downstream power switch for Port…
Part Number: TUSB4020BI-Q1 Other Parts Discussed in Thread: TPS2561 Could you tell me the meaning of PWRCTL_POL in TUSB4020BI-Q1? I don't quite understand the function corresponding to the high and low status of this pin
Part Number: TUSB4020BI-Q1 A device attached to one of our TUSB4020BI-Q1 downstream ports needs to have it's power cycled occasionally.
Is it possible to do this via the TUSB4020BI-Q1 or would we need to add extra logic to the PWRCTL1 signal? (I couldn…
