I am developing an off board power switch that will use a mosfet to switch power to not only the magni but other custom boards we use. I have noticed that when plugging in batteries directly to the magni there is sometimes a spark that I believe would be from inrush currents. Is there any documentation on whether or not there is inrush limiting on this board. I note Q903 looks to be the main power switch mosfet for the MCB but I am unsure if it does any inrush limiting. I have measured many hundreds of amps during plugin using a current sense resistor and oscilloscope. I plan to have soft start on my power switch and want to make sure it is specc-ed correctly to not be overwhelmed by the magni’s power draw on turn on.
Any information regarding it’s turn on characteristics are appreciated.
