Technical Data

4.1

Absolute Maximum Ratings

Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation

under these conditions is not implied. All voltages are referenced to GND unless otherwise specified.

Operation above the absolute maximum ratings may lead to instantaneous device failure. Operation of the L6364

between the operating ratings and the absolute maximum ratings leads to a reduced operating lifetime.
