✅ Nordic Semiconductor Power Profiler Kit 2

✅ Nordic Semiconductor Power Profiler Kit 2 - Review [2021]

2 роки тому

Nordic Semiconductor has launched Power Profiler Kits 2 in Dec 2020.
It is a nice little tool for current measurement, very useful when you are developing low power battery-based embedded system design like wearables, personal trackers, battery-powered data loggers, etc.
I have shared basic features of the power profiler, show a demo of how to use it, and then also talked about limitations of power profiler kit 2 which are important to understand before buying, and then I have shared what other tools are available in the market if nordic power profiler is not suitable or your requirement.

Well done Pallav for an excellent video on the power profiler. Thanks for taking the time and trouble. All the best from a cold and wet English town called Littlehampton. 👍

Great video about our Power Profiler Kitt II. Thanks for sharing.

Thank you, Glad you liked it.

@@PallavAggarwal I have just bought and started to use this kit. Your video was invaluable. Much better explained than the videos provided by @ Nordic Semiconductor

Very nice.. and clear explanation

@krish2nasa 2 роки тому

Excellent explanation. What was its behavior when there is a range change happens? how fast can it happen? Thank you very much.

@PallavAggarwal 2 роки тому

You will not know, it is managed internally by the profiler hardware and firmware. You will get accurate results. Check the datasheet of power profiler for more details.

I understand it can drive power for the DUT between 0.8v to 5v , but at what increment?

@PallavAggarwal 2 роки тому

They have given range 800 to 5000 so 1mv level step but accuracy of output setting will be roughly 20-30mv. General we don't need very high accuracy voltage output, do we?

@udifink 2 роки тому

@@PallavAggarwal My app requires driving 0.8v to an IC and possibly slightly more. In our existing analyzer, we incremented the voltage in 0.01v increments because somehow the sense resistor caused the processor to fail some of the tests when measuring power. We ended up running it in 0.84v to get to a stable point (trying 0.81,0.82,0.83 first). I followed the schematics of the PPK-II. The ADP1708 LDO_Adjust pin is connected to POT1on the I2C potmeter block, which is driven by an mpc4451 I2C quad digital pot (100Kohm). given it is an 8 bit device, we are limited to (5-0.8)/256= 16mV in the best case. I see that the host software is open, but the FW is closed. You could hack an extra 5K digipot in series, so you would get extra 20 divisions between each step of the 100K pot, but you would need external SW to control it due to the closed firmware.

@PallavAggarwal 2 роки тому

That's great. That's for sharing. I did not see the schematics yet. Series resistance will create problems with high current. Also do you really think accuracy of output voltage is that important which will worth the effort?

@jigyashukumar2697 Рік тому

what is your thought on "current ranger "

@PallavAggarwal Рік тому

I have never tried that.

@debugstore 2 роки тому

Is the Power Profiler Kit 2 able to autorange?

@PallavAggarwal 2 роки тому

Yes, it has auto ranging and shows graph also which is the big advantage vs just numerical display type meters. Please watch the video and you will understand.
