Output voltage diagnostic (VMON bit, STATUS 1 register) characteristics
If the output voltage is lower than the min. value the VMON I²C bit is set to 1.
If VMON=0 then V
If VMON=1 then V

otherwise stated. Typical values are referred to T
software description section for I²C access to the system register.
Output current diagnostic (IMON bit, STATUS 2 register) 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.
