https://devzone.nordicsemi.com/f/nordic-q-a/44824/chip-consumes-6ma-in-system-offI have 2 custom made boards. I took the first board. I tested low power consumption. And it WAS working. Made multiple tests on i2c, BLE, GPIO, Flash memory... All worked fine. Then i got back to test low power again and low current consumptionen-USTelligent Community 13Thu, 14 Mar 2019 13:49:32 GMThttps://devzone.nordicsemi.com/thread/176219?ContentTypeID=1Thu, 14 Mar 2019 13:49:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:267f6cc8-d827-482c-9a3a-ff83301d63dbquadrotis<p>It&#39;s KORAD KD3005D</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/176215?ContentTypeID=1Thu, 14 Mar 2019 13:43:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:af70d98a-664c-453a-8367-183ac148e5cbStian R&#248;ed Hafskjold<p>Ahh ok, I see. That&#39;s not good.&nbsp; Glad you figured it out though. Can I ask what type of power supply you are using?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/176204?ContentTypeID=1Thu, 14 Mar 2019 13:29:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6bc24f7c-f5c0-4aad-8072-fc1aafa1d9f9quadrotis<p>Sorry, i don&#39;t have schematics.</p> <p>But it seems like i&#39;ve found the problem after i broke my 3-rd board.</p> <p>For those who will face the same problem:</p> <p>The problem was in my power supply. When i switch it of - it generates high voltage spike.</p> <p>This spikes, seems to be, damaging the chip only a bit. So it continues to work but without ability to go to system off.</p> <p>After several On/Off cycles chip starts to consume over 100 mA and stops responding.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/176170?ContentTypeID=1Thu, 14 Mar 2019 12:24:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bae032bc-334e-472c-8d4e-428039102cd4Stian R&#248;ed Hafskjold<p>Can you please post the schematics for a review.
