Part Number: TPS2042 Other Parts Discussed in Thread: , TPS2041 I made a circuitry to power 2 usb port using TPS2042.
I try to test overcurrent output, by applying a load on the power bus of the usb port, in order to soure a current of 1A. but OC output…
What percentage of the boards are not working?
If there is not enough voltage at VBUS, there is likely an issue with the TPS2042 device, the TUSB2046B does not handle the VBUS directly.
Can you confirm if on the non-working boards does the TUSB2046B stay…
Part Number: TUSB2036 Other Parts Discussed in Thread: TPS2042 , TPS2044 , When I connect my USB Hub to usb port on a mac, I receive notification "USB Devise disabled" like this
The schematic is show here.
How should I fix this Schematic?
Please…
Hi Venkatesh,
The outputs of TPS2042 OCz likely require external pullups, please check.
Per USB spec, the upstream DP line should only be pulled high when an upstream port is connected.

Hi Roland,
USB hubs are "dumb" devices, so they have no capability to emulate DP/DM signaling from a USB host while unconnected. What kind of behavior does the device require to boot up? Is it just looking for VBUS to go high? Hubs can either…

Part Number: TUSB2046B Other Parts Discussed in Thread: TPS2042 Hello E2E community,
I used TUSB2046 to design a hub with one upstream port (USB type B), 2 downstream port (USB type A), and one port connected to an MCU. When I plug the upstream port to…
Hi, Sai loo,
You are correct. All those below parts share same UL report and the test module is TPS2044B, so the protection current is 5A. What's your concern about it?
TPS2041, TPS2042, TPS2043, TPS2044, TPS2045, TPS2046,
TPS2047, TPS2048, TPS2051…
Part Number: TUSB2046B Other Parts Discussed in Thread: TPS2042
Hi all!
I've been facing an issue regarding to the TUSB2046B USB HUB. The PCB I have developed is attached to the USB Port of the RPI-Zero.
When i start the device, it seems the 5V is…
Other Parts Discussed in Thread: TPS2042 , TUSB2036 Hello,
I have a problem with the TUSB2036 in combination with the TPS2042. My upstream device is a 'PICO-IMX6-EMMC' system on module.
I've connected it much like the schematic in '6Mhz Bus-powered…
