ELECTRICAL CHARACTERISTICS (continued)
(V
OUTPUT = 12G = 3.3G = OPEN, INPUT = PRES-DET = PGND = GND, T
are at T
Note 1: 100% production tested at T
Note 2: PWRGD asserts a time t
Note 3: The UVLO for the 3.3V supply is sensed at 3.3S+.
Note 4: This is the time that ON or AUXON must stay low when resetting a fault condition.
