Other Parts Discussed in Thread: TEST,
There is an operation problem during the test after PCB fabrication, so please contact us.
If the PA6 pin of MCU is High and all other pins are Low (including power), USB connection is not possible.
When I check the block diagram of the datasheet, the output is connected to the input, and when I check V+, 1.xx V is floating.
When the part is removed, it is directly connected to USB, and even when 3.0V is connected to V+, it works normally.
I would like to know the cause of the reason why the level of 1.xxV is measured in V+ and USB connection is not possible due to this.
The circuit diagram of the USB type-C connector connected to the TLV9002S is as follows. Please refer.
