DA9061 shuts off Buck3 without reason
Posted byTKL10 points 10 repliesHi,
in a new product we use the DA9061-66 with an iMX6ULL. The product is finished and we already had market launch.
Generally everything works fine (passed all EMI tests with above the norm levels without problems, no problems during our development phase) but unfortunately in our long time tests we experience problems. After ~1-21 days on some of our devices we see that the DA9061 shuts off the Buck3 regulator which supplies our DDR3 RAM (we use one 16-Bit DDR3 IC). This leads to a freezing device from which there is no other way out than turning the power off and on again. So market launch is stopped until we resolve the problem.
At the moment we have no idea why it happens.
Here is what we already tried:
- We monitored that there are no telegrams on I2C which shut off the regulator when the device has a failure.
- On a device in failure mode, we read out the registers of the DA9061 with the development board, I will attach the file to this post as .pdf file, but it is a .txt file. We found nothing unusual. Buck3 is enabled. Maybe we overlooked something.
- On this failing device we monitored the current on the Buck 3 rail and there was no overcurrent event.
- Vref of the DA9061 on device in freeze was 1,19V
- Vcore of the DA9061 was 2.5V
- Only disconnecting the power seems to get the DA9061 back to normal work
- It seems totally random when it happens. On one device it happened after 30 minutes, next run after 20 days. Same software, same environment and so on
- We tried to force the error with different approaches but until now we didn't find a way to reproduce it. It only happens completely random, but it seems as if it always happens on the same devices.
- Our system logs (we use Linux) don't show anything. The system just stops without any error message probably when the RAM voltage fails. Until now we didn't get a trigger to the falling voltage, we are still trying to. Its a bit of a problem with the long time between the error occurence.
At the moment the most plausible explanation to us is that the DA9061 chips on this devices are somehow damaged.
We already submitted schematics and layout to Dialog but got no feedback to them now for 24 days, which is very disappointing to me.
Has anyone here ever had a comparable thing with this PMIC or this PMIC family? We are at a dead end here as it seems.
Thank you very much,
Best regards,
Torben

Hello Torben,
we are in a very similar situation as you are. We are using a DA9063 device in a product that will be released in a few weeks.
In some products the DA9063 devices now show the same behavior as you already described - they suddenly shut-off the BUCK-Peri DCDC after it has been running normally for several days.
我们的调查结果s are as follows:
——/音序器似乎DA9063内部逻辑still running as nRESET pin and other voltages remain active while BUCK_PERI is turned off
- No I2C communication with the DA9063 when the BUCK-Peri DCDC is shut-off (one thought was, that the regulator is switched off via I2C)
- We connected an I2C sniffer to the devices that had switched off the BUCK_PERI regulator to read out the status and control registers:
- BPERI_CONT (0x25): 0x01
- according to the register content, the regulator should be running
- we measured 380mV remaining voltage at the output
- when we write a 0x00 to BPERI_CONT the voltage drops to 200mV -> PullDown is enabled when BUCK_PERI is disabled
- when we now write 0x01 to BPERI_CONT the regulator turns on again with its correct output voltage (even on devices that switched the off the DCDC before)
- Comparing all status and interrupt registers we found now unusual register content. The comparison to a working device showed no difference in the register contents.
- After a powercycle BUCK-Peri is working correctly again
Until now we have not been able to force the failure.
- We applied different loads and overload to the DCDC (including sudden load steps)
- We applied external voltages to the device (below and above the DCDC output voltage)
To answer your question Torben, yes we see the almost exact same behavior as you described with a device of the same family. And we are running out of ideas for the further investigation.
@Eliot: I would appriciate very much if we could get in contact and work on a solution toghether. This is a very serious issue for as as we are very close to the release of our product.
Thank you very much for your help.
Best regards

Hi Florian,
that sounds very much like a comparable problem, except we do not measure any voltage left on the disabled regulator, this seems different.
We are still working on the problem here. No luck forcing the error until now here either.

Hello together,
I think we have nearly the same problems. Have you already found a solution in the meantime?
Problem description:
We are using the DA9061 on our i.MX6ULL based System On Module.
There we have SOM’s with the DA9061 which are working without problems, but some device switch of the buck2 (used for 3V3 IO voltage) without any reason after some time. We have some devices where this happens after some hours, next run several days or weeks and most of the devices doesn’t have the problem. The test software doesn’t use the Linux PMIC driver. This means we have no communication between host CPU and the PMIC, but the problem occurs anyway.
Within the Freeze condition we measured ~0,8V at buck2. But all other voltage rails are still alive at this condition:
Buck1 = Core voltage = 1,4V
Buck3 = DDR voltage = 1,35V

Hi,
sounds like the same problem. The solution for us was to switch the mode from auto to synchronous mode / PWM. In this settings we had no problems anymore. You might see an increased radiated EMI because of this change.
Generally we could reproduce the problems only on a few chips. We had 150 test devices running and only on one the problem was reproduceable within a reasonable time (<48h). On this one we couldn't see the problem again after the change (tested for a month). The device is in the market now for 1 year and we have no problems with it.

Hi Torben,
many thanks to your fast answer.
Yes, I think it is the same problem. We did tests with 25 devices. Two of the lot had the problem, but it tooks 2 weeks with the first device and more then one month with the second one, till the problem occurs. And next to the 25 devices we have now one "bad" device, where we can reproduce the problem within some hours.
So with the next step we will also try synchronous mode / PWM. I keep the fingers crossed, that it also works on our devices.
Did you get also an official reply from dialog to this topic?

Hello Torben,
I will reach out directly to you.
Kind regards,
