1Device switched on into existing short circuit (see diagram Determination of I D(lim)). If the device is in on condition
and a short circuit occurs, these values might be exceeded for max. 50 μs.
2Integrated protection functions are designed to prevent IC destruction under fault conditions
described in the data sheet. Fault conditions are considered as "outside" normal operating range.
Protection functions are not designed for continuous repetitive operation.
