Mr. Amy, I request your help.

I have the problem that Luca by a short circuit, but additionally the ...

Sir, please discribe the fault phenomenon of your device.

amy

Please remove the resistance(L68) and measure the voltage of the point in the picture.
If it isn't 5V, please replace U38(TPS63000DRCR).

amy

When you connect the scope to your computer, is the device recognized by computer?

amy

Please test the voltage of these points and check whether the voltages are consistent with the marked values.

amy

Please confirm whether the voltage if this red markpoint is 1.8V.




The point (you said it is short circuit) in the picture below is interlinked with the point 1.8V in the picture above.

amy

Do mean the 1.8v voltage become 0V when the 0 ohm resistance of L33 is welded?
The 2.7V in the figure below should be 1.8V, right?



Remove L33, C214, C216, C213, and test whether there is short circuite on the two pads of C213.



If all the above are satisfied, it can be determined that had1511 is faulty.

If you can't find it, you can contact your seller to get the chip or get it from us, but you need to pay the freight from China to you.

The complete model of the chip is HMCAD1511. Please try to find it online.
