Part Number: TIDA-01580
We are making the TIDA-01580.
And already made the Kit(PAB and SMT) for it.
However, It is not working.
We are found a problem about the power.
This problem was short circuit about VBAT and GND.
I was attach file.
I marked that problem was the connected of theVBATT and GND at Battery circuit file.
And also, VBATT node was connected all GND(also GND1).
Also, VDDS node was connected all GND(also GND1).
This problem marked at Programing Connector file.
And Boost and Buck-boost of power circuit seems okay(Converter circuit file).
Made with the same data.(TIDA-01580, www.ti.com/.../TIDA-01580
i'm not modify a reference schematic of the TIDA-01580.
I'd appreciate it if you could check the problem.
Hello Daeho Kim,
Thank you for using TIDA-01580 for your design.
The gerbers/layouts on TI web are fully tested and there are many customers worldwide who have fabricated boards using these files.
Regarding your query, I would like to understand more:
1) Do you see a short between VBATT & GND (as shown in your first image)? If yes, did you check the capacitors C41 & C42?
2) Do you see a short between GND1 & VDDS? If yes, this is because VDDS and VBATT are shorted through L5 (Main board Schematic Page -3).
I think you need to check on the blank board (non-assembled) for any shorts and also check if there are any components shorting after assembling.

In reply to Sanjay Pithadia:
I'm sorry for delay of reply.
So, Sorry but, I can't check at now.
Because, TIDA-01580 Kit is now in the manufacturer.
I will upload it again after confirmation.
In reply to Daeho Kim:
I removed the C41, C42.
But, it still shorted of the VCC and GND.
Which part of the circuit should I check?
Please, check and reply.
Without having physical board with me, I would suggest you to trace from the input on where the short is. Start disconnecting and eliminating the root cause on each stage and check.
I recommend powering your board with bench power supply (with current limit) to check the shorts.
First, Thank you for reply.
I was check the circuit about your suggestion.
And i found the problem. It was wrong solder direction of parts(R30, R33).
So, I will replace the direction and test.
And i will let you know the result.
Hi, Thank you so much for your help.
This was an R30, R33 soldering problem.
Currently, It works.
