Part Number: TUSB4041I Tool/software: Hello, I want to implement the most simple possible 480Mbps 12-port downstream USB HUB. Most simple from HW and SW perspective: plug&play chip, not requiring addicional registers configuration, EEPROM, and other features…
Hi Ryu:
Ryu Yamashita said: Does the current consumption rise to about 300mA for both VDD and VD33?
only for VDD, VDD33 is still normal
Ryu Yamashita said: Also, will this current consumption during reset ever be added to the datasheet?
not in datasheet…
Part Number: TUSB4041I Other Parts Discussed in Thread: TUSB4020BI Tool/software: In TUSB4041I debugging, VBUS has no voltage when no load is connected to the downstream port. After investigation, it was found that PWRCTL1/2/3/4 is at a low level (0…
Part Number: TUSB4041I-Q1 Other Parts Discussed in Thread: TUSB4041I Tool/software: Hello,
We are using the TUSB4041I in an on-board USB switch application for a power consumption sensitive (automotive) environment. During testing, we have noticed anomalously…
Part Number: TUSB4041I
Tool/software:
Hi Shashank,
In one of the custom PCB, TUSB4041 port one always shows " port1: over-current condition " and hold the PWRCTL1/BATEN1 pin always low. But another PCB its working as normal.We have isolated all the…
Hi Margub:
Sorry replying late, I didn't noticed the schematic was sent to message box.
For schematic,
need to remove R96 to use i2C mode.
Need to remove R124 to enable power switch.
need to remove R126 for individual mode
need to remove R125…
