In the nRF54L15 DK / Nordic documentation, the PPK2 measurement is recommended at 3000 mV. I would like to know whether iten-USTelligent Community 13Wed, 13 May 2026 11:36:52 GMThttps://devzone.nordicsemi.com/thread/566331?ContentTypeID=1Wed, 13 May 2026 11:36:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56e6a509-ada6-47c6-ac5b-ab85a05df8feSwRa<p>Closed as a duplicate of&nbsp;<span>#359959&nbsp;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/566294?ContentTypeID=1Wed, 13 May 2026 05:45:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ae17cc82-22fd-4a32-9e28-ad1453a6a733xiyan<p>I also found a new issue during the measurement.</p> <p>I flashed a System OFF test firmware to the nRF54L15 DK. When I use the PPK2 in source meter mode, set the supply voltage to 3.0 V, enable the PPK2 power output, and keep the nRF54L15 DK power switch turned off, the average current is above 60 uA. This is clearly much higher than expected for System OFF.</p> <p>However, if I connect the debugger USB Type-C cable to the DK and turn on the DK power switch, the measured current drops back to about 0.88 uA, which matches the expected System OFF current.</p> <p>Could you please explain why the measured current is above 60 uA when the DK power switch is off and the board is powered only from the PPK2 source meter, but becomes normal when the debugger USB Type-C is connected and the DK power switch is on?</p> <p>Is this related to the nRF54L15 DK power path, the debugger/interface MCU, leakage through the DK circuitry, or an incorrect PPK2 connection/configuration for measuring System OFF current?</p><div style="clear:both;"></div>
