Hello Support Team,
I am currently working with the Matter contact sensor sample (ncs\v3.4.0\nrf\samples\matter\contact_sensor) on the nRF54L15 Development Kit (DK).
As part of my application requirements, users need to keep two or more buttons depressed for extended periods. However, when pressing the SW1 button on the DK, the Power Profiler Kit 2 (PPK2) registers a constant high current draw of approximately 20 mA. This current consumption significantly exceeds what would be expected from internal pull resistors.
The board is powered via the onboard nPM1300 PMIC. Despite testing various configurations—including both internal and external resistor setups,using sense-mask,using gpio_pin_configure_dt —the current spike persists consistently as long as the button is held down.
Since the final product will be battery-powered, this level of power consumption is a critical issue for the design. Could you please advise on potential solutions to resolve this behavior, or let me know if this indicates a hardware defect on the nRF54L15 DK?
Thank you for your assistance.
