5 Current Limit

When IOUT reaches the current limit threshold, ICL= KCL / RILIM, the device can switch off immediately, or the device can remain enabled and limit IOUT. The HSS-MOTHERBOARDEVM enables multiple variants use case as any device can be populated in the snap-off daughtercards or on the footprint directly on the board. In the case that the device remains enabled (and limits IOUT), the thermal shutdown or energy limit protection feature may be triggered due to the high amount of power dissipation in the device. Check the data sheet for the device being used to see what the range of current limit can be.
