Part Number: TUSB320EVM
Hi All, We are looking to build a breakout for connecting a OTG device to the Samsung Galaxy/Note Series (Note 9 and above, Galaxy S9 and above). The requirements are as follows:
To write it in one line, we are essentially building a OTG board with (fast) charging capability. Based on our limited research we think the best way forward is to use the TUSB320 configured for DRP in GPIO mode.The queries that we do have with respect to TUSB320EVM are:
TUSB320EVM User Guide
With TUSB320 you can create a USB-C with a Type-C port that indicates that a certian current level can be provided to the sink device (Samsung Phone). With TUSB320 you can present default charging current (500 mA/ 900 mA),1.5 A or 3.0 A charging in GPIO mode. When you say OTG what functionality are you looking for specifically? Are you using data with this device or is it only a charging device? Your device will have a Type-C port correct?
1. TUSB320 when in DRP mode will configure itself based on what voltage levels are present on the CC lines at the time of attachment. When nothing is attached to the CC lines TUSB320 is in an unattached state.
2. CSD17313Q2 is implemented as an additional switch from micABVBUS_OUT to TypeC_VBUS and limit current in one direction. Since Vbus can also come from Type-C connector CSD17313Q2 is used to limit current from TypeC_VBUS to micABVBUS_OUT when TPS25910 is disabled.
3. CC controller is the most simplistic solution for providing charging currents above USB default settings with Type-C ports.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
