When the error is cleared, VBUS has to be disabled and enabled to restart the charger:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ps_npm1100/chapters/charger.html#charger_error_cond">https://infocenter.nordicsemi.com/topic/ps_npm1100/chapters/charger.html#charger_error_cond</a></p><div style="clear:both;"></div>
