Operating Characteristics).
Note 3: The current-limit slow-comparator response time is weighted against the amount of overcurrent; the higher the overcurrent
condition, the faster the response time (see the Typical Operating Characteristics).
Note 4: 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 5: The current available at GATE is a function of V
GATE
(see the Typical Operating Characteristics).
