x 7.5礎 + 25mV (see the Typical Operating Characteristics).
Note 4: The current-limit slow-comparator response time is weighed against the amount of overcurrentthe higher the overcurrent
condition, the faster the response time (see the Typical Operating Characteristics).
Note 5: The startup period (t
START
) is the time during which the slow comparator is ignored and the device acts as a current limiter
by regulating the sense current with the fast comparator (see the Startup Period section).
Note 6: The current available at GATE is a function of V
GATE
(see the Typical Operating Characteristics).
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.
