0 = No UVLO fault
1 = UVLO fault
Set whenever a circuit isolation protection fault condition
occurs as a result of an undervoltage lockout condition on
one of the main supply inputs. This bit is only set if a UVLO
condition occurs while the ON pin is asserted or the MAIN
control bits are set
0 = Die Temp < +160°C.
1 = Fault: Die Temp > +160°C.
Set if a fault occurs as a result of the ISL6112’s die
