https://devzone.nordicsemi.com/f/nordic-q-a/124563/npm1300-usb-charger-default-configurationWe are designing a board around nRF54H20, and nPM1300, with some peripheral on VSYS, some on V3.0 BUCK2 and other are on V1.8 BUCK1. We also have detachable battery in place. We would like to know if there is any other way like &quot;hardware configurationen-USTelligent Community 13Fri, 26 Sep 2025 10:36:26 GMThttps://devzone.nordicsemi.com/thread/549883?ContentTypeID=1Fri, 26 Sep 2025 10:36:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5c48871e-6608-4c87-a294-34236faff323Tomi Koskela<p>Hello,</p> <p></p> <p>Unfortunately the default VBUS current limit setting is 100mA and would need to be programmed through TWI to 500mA. Would it be possible to disable one of the bucks at startup (connect VSETx pin to GND) and turn this on only after nRF54 is powered and VBUS current limit is programmed higher? Not sure how the powering of the peripherals is split between the rails, but something to consider as a workaround. If the battery is connected the device will be in supplement mode in the startup if VBUS is connected (VSYS is powered from VBUS and battery at the same time). Of course this does not help if the battery is drained.&nbsp;&nbsp;</p><div style="clear:both;"></div>
