ELECTRICAL CHARACTERISTICS (continued)
(VCC, IN1–IN4 = +2.7V to +5.5V; ENABLE = MARGIN = MR = ABP = TRKEN; TA = -40°C to +85°C, unless otherwise specified.
Typical values are at TA = +25°C.) (Note 1)

Note 1: Specifications guaranteed for the stated global conditions. 100% production tested at TA = +25°C and TA = +85°C.
Specifications at TA = -40°C are guaranteed by design.
Note 2: The internal supply voltage, measurable on ABP, is equal to the maximum of IN1–IN4 and VCC supplies.
Note 3: Differential between each of the OUT_ and the SYNCH ramp voltage during power-up/down measured as VOUT_ - 2 x
VSYNCH.
Note 4: FAULT timeout starts to count at the beginning of each sequence of power-up/down and clears when the programmed
OUT_ voltages track successfully.
