Note: 1. In case of SC OUTx to Vs the switch off current is always higher than the start value of current regulation (∆|IOUK| = |IOUK| - |IOUmax|

2. Guaranteed by design

3. Value is tested down to 6V. For supply voltage below 6V on increased current can be fed back in the device via a protection path
