DA9062 programming

Good morning all,

I use a DA9062 in order to control the power supplies on a device and I would like to programming it with my tool, trough IIC bus.
I have tried to write and read the registers and I can do it. I can't  do the OTP programming..

In order to do the OTP programming I done these steps:

  • I have applied 7,5V to TP pin;
  • powered the DA9062
  • I have writed all registers
  • I have powered off the 7,5V. At this point the DA9062 work correctly but, if I restart it, the DA9062 doesn't work. Its OTP memory is empty..

Which passages I miss?
What are the steps that I must do do for an OTP programming?
What are the command that I must to send?

Thank you all for the support,
have a nice day.
Diego.

Hello Diego,

Hello Diego,

It sounds like you are putting the PMIC into powercommander mode and then not succesfully programming the part. 

The process for programming the part is in our application note:

https://support.dialog-semiconductor.com/system/files/pmic_resources/AN-PM-080_In-circuit_programming_DA906x_2v0.pdf

We have also have a ICP GUI aswell, this is used along side the ICP board we have.

Do you have the ICP board?

Kind regards,
Elliott

Hi,

Hi,

I have read some application notes, including AN-PM-080_In-circuit_programming_DA906x_2v0.. 
I have the DA9062 EVAL board. For the firsts prototipies I have used this board for OTP programming. In phase of production we don't use eval board/programmer.. We use a JTAG tool that let to do some  operations, including operations writing/reading on IIC bus.
We would like to use this tool for OTP programming.. How we can do this?

Thanks,
Diego.

Hello Diego,

Hello Diego,

Did you have the programming issue with the eval board or the JTAG tool?

Kind regards,
Elliott

I have the problem with the

I have the problem with the JTAG.
With the evaluation board I can program OTP the device. I don't understand where is the problem..
By reading the DA9062 datasheet I understood that, if I must to program OTP, I only apply 7,5V at TP pin.. But it doesn't work correctly..

There are other command that I must to send on IIC?
There are other actions that I must to do?
What can I check?

Thank you,
Diego.

Hi Diego,

Hi Diego,

I would recomend using the ICP board, this bought can be aquired via Avnet. The issue may stem from not having the correct driver on your JTAG board.

Kind regards,

Elliott
