Notes:
1.
Integrated protection functions, as described in this data sheet, are designed to prevent the destruction of the IC and these fault conditions are considered ‘outside’
the normal operating ranges. It is important to note that the protection functions integrated into this device are NOT designed for continuous repetitive operation.
