ITS4060S-SJ-N overvoltage protection
So we have some ITS4060S-SJ-N, so I decided - why not just test it? Well, it passed up to 40V straight through to the OUT pin when the load drew around 20mA. That indicates that it won't disconnect the load if the supply voltage is too high. I suppose I would need something like http://www.ti.com/product/TPS2663 and the increased cost if I wanted that functionality. Oh well!
