values are at V
( Typical Operating Circuit , Q1 = Q2 = Q3 = Fairchild FDB7030L, V
erwise noted. Channels 1 through 3 are identical in performance. Where characteristics are interchangeable, channels 1 through 3
are referred to as X, Y, and Z.)

Note 2: All devices are 100% tested at T
Note 3: The slow-comparator threshold is adjustable. V
Note 4: The current-limit slow-comparator response time is weighed against the amount of overcurrent, the higher the overcurrent
Note 5: The startup period (t
Note 6: The current available at GATE is a function of V
Note 7: After a fault triggered by the fast comparator, the gate is discharged by the strong discharge current.
Note 8: Each channel input while the other inputs are at +1V.
Note 9: Each channel input while any other input is at +3.3V.
