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…
Part Number: TUSB4020BI Other Parts Discussed in Thread: TPS2561 , TUSB1210 Dear，
I have a question to interrupt you, our customer used TUSB4020,and he found that USB_DN2 could recognize 480M high speed, but USB_DN1 only recognized full and low speed…
Part Number: TUSB4020BI-Q1 Hi All,
We have 2 questions when using TUSB4020BI-Q1 .
1. Since we only need the TUSB4020BI-Q1 as a USB 2 HUB, no power switch or SMBus/I2C is needed.
May I know how to configure below pins?
SCL / SMBCLK (Pin 2) …
Part Number: TUSB4020BI-Q1 Hi,
I'd like to know why we can't see the USB 2.0 HUB in Linux using "lsusb" command.
we checked voltages:
1. VDD_1P1 (Equal to 1.16 on board)
2. VCC_3V3 (Equal to 3.34 on board)
Note: I understood the the EEPROM…
Part Number: TUSB8020B-Q1 Other Parts Discussed in Thread: TUSB4020BI-Q1 , Hi, Team
Hope you are doing well!
My customer is evaluating our TUSB8020B-Q1 and TUSB4020BI-Q1.
From their datasheets, they both need to use an external EEPROM.
When customer design…
Part Number: TUSB4020BI-Q1 Other Parts Discussed in Thread: TUSB4020BI May I ask what is the voltage tolerance value of D+/- output of TUSB4020BI-Q1 HUB? It is not specified in the manual. Will D+ short circuit to VBUS 5V damage the HUB?
Part Number: TUSB4020BI Hi Team,
Our customer would like to connect USB 2.0 HUB(TUSB4020BI) and USB PD adapter to same Type-C connector on board.
So, USB2.0 communication by HUB(device ① (UP)=>HUB=>device ② (DOWN)) and power supply(DFP 9V/2A) by USB…
Part Number: TUSB4020BI Hi Tech Support:
We areusing TUSB4020BI in our application. In our design, we don't get VBUS from the host, so we have VBUS always connected to a 5V source through the appropriate resistor divider per the data sheet.
When a…
