Disable and monitor feature

Several disabling means are available to externally disable the IC:

Driving the CTRL pin low (CTRL_DIS): this occurrence immediately puts the device

in the low consumption mode; when the CTRL pin is left free, the internal biasing mean

pulls up the voltage above the threshold entering the soft-start procedure.

Driving the CTRL pin high (AN_DIS): a CTRL voltage higher than the threshold for

a time longer than Tdis causes the device to enter the low consumption mode. The

ART timer performs an auto recover procedure after Trec.

Anytime the HVLED001A device enters low consumption an internal pull-down discharges

the soft-start capacitor and resets the soft-start time.
