The device provides embedded protective functions, which are designed to prevent IC destruction under fault
conditions described in this data sheet. Fault conditions are considered as “outside” normal operating range.
Protective functions are neither designed for continuous nor for repetitive operation.
8.1
The maximum load current
itself. Depending on the total short circuit impedance higher current over shoots may occur. A limited auto-restart
function is implemented. The number of restarts is dependent of the
for details.
