ELECTRICAL CHARACTERISTICS (continued)
(V
values are at V
otherwise.) (Note 2)
Note 2: Production testing done at +25NC. Overtemperature limits are guaranteed by design and not production tested.
Note 3: The current-limit thresholds are programmed through the I 2 C interface (see the Register Map and Description section and
Note 4: Functional test is performed over thermal shutdown entering test mode.
Note 5: R
Note 6: If Class 5 is enabled, this value is the classification current threshold from Class 4 to Class 5, and classification currents
Note 7: Default value. The fault timer can be reprogrammed through the I 2 C interface (TLIM_[3:0]).
Note 8: Guaranteed by design. Not subject to production testing.
