nPM1300 load switch peak currenthttps://devzone.nordicsemi.com/f/nordic-q-a/123802/npm1300-load-switch-peak-currentHi About nPM1300 We will use load switch to drive haptic function and its peak current may up to 0.4A~0.5A@25us duration, I see the spec show the load switch with maximum 100mA capability, but no current protection information.

After the soft start there is no current limiter on the load switch.
