bq51013evm-725 design

Hi

The PCB and Schematic are part of the EVM user’s guide which can be found in the bq51013EVM-725 product folder.

Also in the product folder are the Gerber files for the PCB.

But if you are thinking about a smaller solution the EVM would be a very rough starting point.  Everything is correct but it is not optimized for size.

We have another smaller prototype design which is 5mm X 15mm that may be a better fit for your application.

Hi Bill,

What I want is to re-draw and re-make this PCB board of the bq51013EVM-725, it is good if you can provide me the orginal ".pcb" and ".sch" files instead of PDF version, so that I can use software to re-design it.

And one more thing is regarding the IC chip (bq51013YFF) on the receiver, do I need to program it before integrating with the receiver circuit if I have a new one ?

Regards,

Hi Bill,

I have viewed the gerber files and for re-design purpose,  what I need is the original schematic file instead of PDF file since it is not possible to convert PDF to .sch file.

Pls send me a copy of original schematic file of the bq51013EVM-725 if possible. Thank you.

Hi,

I am not able to open the files since somehow they are invalid.

Could you send them again and maybe you can try to open them before sending to me?

Thank you.

HI,

After unzip the folder called "3884.bq51013EVM-725 Design File PCAD2004", I have two files named "HPA725A.pcb" and "HPA725A.sch", I could not open both.

There is no file called PCAD2004.

You requested the design files for bq51013EVM-725.  I sent you the design files HPA725A.PCB is the PCB design file, HPA725A.SCH is the schematic files.

You will need to open the files with the design package PCAD2004.  I cannot send you that design tool.

What PCB design tool are you using?

Bill

Hello,

Regarding the receiver, the prototype we have developed has some thermal issues when delivering close to 5W and turns off. Could I take a look at this smaller 5mm x 15mm design, please? I don't have the PCAD2004 software, so I wonder if you could send a PDF file just to take a look.

Is it suited for delivering near max (5W) power? Also, I read throughout the forum about the possibility of delivering 7.5W. Could you provide me with some ideas on how to make it work?

Thanks in advance.

Hello Bill,

I have the bq51013AEVM-765 evaluation board and the device somehow lost its programming, I am assuming, I had this device on the transmitter board and the transmitter board was powered by a stable 19V. The receiver just all of a sudden shut off and I figured it maybe due to thermal shutdown but I didn't have a load on the device. Is there a way to reprogram this chip or what would I use to try to reprogram the chip? Also, if I buy this chip does it come preprogrammed?

Thank you,

Chad Johnson

Lingyu Liu, Please look at the forum as the Eagle design files are on the internet in .BRD and .SCH form for both the receiver and the transmitter.
