ELECTRICAL CHARACTERISTICS (continued)
(V AGND = 32V to 60V, V EE = V DGND = 0V, T A = -40 N C to +105 N C. All voltages are referenced to V EE , unless otherwise noted. Typical
values are at V AGND = 54V, T A = +25 N C, and default register settings. Currents are positive when entering the pin, and negative
otherwise.) (Note 2)

Note 2: Production testing done at +25 N C. Overtemperature limits are guaranteed by design and not production tested.
Note 3: The current-limit thresholds are programmed through the I2C interface (see the Register Map and Description section and
Table 41).
Note 4: Functional test is performed over thermal shutdown entering test mode.
Note 5: R DOK = (V OUT2 - V OUT1 )/(I OUT2 - I OUT1 ). V OUT1 , V OUT2 , I OUT1 , and I OUT2 represent the voltage at OUT_ and the current
into OUT_ during phase 1 and 2 of the detection, respectively.
Note 6: If Class 5 is enabled, this value is the classification current threshold from Class 4 to Class 5, and classification currents
between 51mA and I CL_LIM will be classified as Class 5.
Note 7: Default value. The fault timer can be reprogrammed through the I2C interface (TLIM_[3:0]).
Note 8: Guaranteed by design. Not subject to production testing.
