Output voltage diagnostic (VMON bit) characteristics
If the output voltage is lower than the min. value the VMON I²C bit is set to 1.

Minimum output current diagnostic (IMON bit) characteristics
If the output current is lower than the min. threshold limit the IMON I²C bit is set to 1. if the
output current is higher than the max threshold limit the IMON I²C bit is set to 0.
