Electrical Characteristics
CharacteristicsDevice switched on into existing short circuit (see diagram Determination of ID(lim)). If the device is in on condition
and a short circuit occurs, these values might be exceeded for max. 50 µs.

Protection Functions1)
Inverse DiodeIntegrated 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.
