Part Number: TPS2071 Hi Support Team.
In the Qualification Summary, the results of ESD-HBM and CDM are described as "See data sheet". However, the datasheet does not show the results of ESD.
Please tell me ESD data (HBM data , CDM data) of TPS2071DAP…
Other Parts Discussed in Thread: TPS2071 , TPS2071EVM-159 Hi,
I'm evaluating the TPS2071 HUB EVM but everytime I tried to plug in a flash drive, it says that the HUB exceeds power. When I plug in a usb keyboard or mouse however, it doesn't say that error…
Other Parts Discussed in Thread: TPS2071 Hi,
I would like to inquire that whether the assertion on reset pin is integral for boot up sequence of the IC or not? can the pin be left always as logic 1? my board is getting direct 3.3V supply and hence it diminishes…
Hi Ben,
According to TPS2044B EVM schematic I would say that this device requires pull up resistors on OCx pins, 10K-Ohm should do it. You could ask this to the Power Management team as they are in charge of this device. Perhaps the USB Interface team…
Thank you for your answser, I modifiy the schematic to solve my problem.
I try it on my board, and on the TPS2071 HUB EVM without the TPS2071DAP, and I modify the card to be like my schematic.
The result is the two board have the same problem. When…
Thanks Elias,
For the benefit of others and complete response, I am also posting the response from Kevin, TI Analog Field Applications.
"Yes, our USB hub ICs TUSB2036 (3-port) /TUSB2046 (4-port) can be commanded by the USB host in your processor to selectively…
Kevin,
The EVM Gerber files can be found in the EVM folder .
There are some reference schematics which i have attached as well. None of them match exactly the gerber files since that board was actually designed by the power management team for the TPS2071…
Thanks for all your help Frank. We decided to use the PCM2912. The board shop orginally didn't want to use TI because of the long lead times, that was why we were looking at the CM-108, but really could only get over seas. So now back to TI. We will…
