Enable and Reset
In order to maximize both the EN threshold accuracy and the current consumption, the device implements two
different enable thresholds:
•
The wake-up threshold, VWAKEUPH = 0.5 V typ.
•
The start-up threshold, VENH = 1.2 V typ.
As soon as the EN pin is detected above VWAKEUPH and VIN voltage is higher than VINH, the regulator turns on
the internal circuitry and waits for the VENH before starting the switching activity. When this occurs, the internal
voltage reference is increased by about 2 ms (typ.) in order to limit the inrush current and perform a smooth
output capacitor charge.
