    Hi Roi,

    1. You will need to ensure the voltage at the enable pin rises above VEN_VOUT_H in order for the device to be enabled. The maximum value of VEN_VOUT_H is 1.25V so I would recommend targeting this voltage to ensure the device always turns on. 
    2. It is difficult to see component values in the schematic you shared. Could you please send a higher resolution image?

    Thanks,

    Sarah
