Other Parts Discussed in Thread: TPS2052B Hi Team, There is 2 patterns for "Exposed Thermal Pad Dimensions" for DGN package in TPS2052B datasheet. http://www.ti.com/lit/ds/slvs514l/slvs514l.pdf Page.41 shows the following. On the other hand, page…
Hello Francy,
Correct. VBUS would be used for a dual-channel switch like TPS2052B if you needed to support USB Device and USB Host/OTG.
Best Regards,
Ralph
Other Parts Discussed in Thread: TPS2052B We are developping a design which uses the TPS2052B to switch power to a couple downstream USB devices. In the low power state of the design, power is removed from the switch Vcc pin, but the enable lines are held…
USB0EPEN is an output to control a power switch. Do not connect it to 5V. It is optional in host mode. We used it with a TPS2052B in our EK-TM4C1294XL LaunchPad design .
Excuse me.
As we check TPS2042BDR spec that show "Additional UL Recognition for TPS2042B and TPS2052B for Ganged Configuration". Where can find "UL Recognized" or "File Number E169910" report?
thanks.

Hi Kaushik
If JP1 is in the left or middle position, which selects the BoosterPack headers or the USB OTG connector, respectively, externally provide 3.3 V to the board, and remove the 3V3 jumper on J101.
The left position is for BoosterPack plug-in…
At a higher level, since you're using PQ4 to output DIVSCLK, you'll want to remove the JP6 jumper on your LaunchPad. If populated, the JP6 jumper connects PQ4 to U4 (TPS2052B power distribution switch). Typically, PQ4 seems to be configured as an individual…
Hi SWAROOP T K,
We can't guarantee that TPS2052/TPS2052B can work stable under 1A continuous current. TI does not recommend using TPS2052 in a new design, TPS2052B is a replaced part. For 1A continuous application, we recommend to use TPS2062/TPS2066. …
Hello Chris,
Yes, I do not see any indication that the VBUS pin cannot supply 5V in Host mode in either the D/S or the LaunchPad design. Incorrect Statement: The USB0VBUS pin does not provide 5V. On the LaunchPad, the TPS2052B is a switch that outputs an external…
