(Note 3)
Note 3: This device is 100% production tested at T
A
 = +25NC. Limits over temperature are guaranteed by design.
Note 4: The input offset current is illustrated in Figure 1.
Note 5: Effective differential input resistance is defined as the differential resistance between V
DD
 and V
SS
. See Figure 1.
Note 6: Classification current is turned off whenever the device is in power mode.
Note 7: UVLO hysteresis is guaranteed by design, not production tested.
Note 8: A 20V glitch on input voltage, which takes V
DD
 below V
ON
 shorter than or equal to t
OFF_DLY
 does not cause the
MAX5969D to exit power-on mode.
Note 9: In power mode, current-limit foldback is used to reduce the power dissipation in the isolation MOSFET during an overload
condition across V
DD
 and RTN.
