Enabled
The LLC OC2 comparator is connected to the LLC_CS pin and its threshold is 700 mV.
3.2.6
Max number of LLC OC2
Size: 2 bits
Sets the number of consecutive LLC OC2 events before shutting down.
Available values are:
•
1
•
2
•
4
•
8
Use
The suggested value is "2", since it is a good compromise between the noise rejection and protection
reactiveness.
The value "1" can be used if minimum intervention time is required: in this case, pay attention because some
noise could trigger the protection.
3.2.7
LLC OVP detection
Size: 1 bit
Enables / disables the LLC OVP comparator.
Available values are:
•
Disabled
•
Enabled
The LLC OVP comparator is connected to the LLC_AUX pin and its threshold is 2.5 V.
3.2.8
Disconnection faults detection
Size: 1 bit
Enables / disables the feedback disconnections faults detection.
Available values are:
•
Disabled
•
Enabled
Use
It is suggested to enable the feedback disconnection faults detection.
Note:
Disconnection faults have always "latched" behavior.
3.2.9
PFC OC2 behavior
Size: 1 bit
Sets the behavior of PFC OC2 protection.
Available values are:
•
Not latched
•
Latched
If the fault is set as "Not latched" the system will try to restart after the time defined by the "Non latched faults
timer" parameter.
If the fault is set as "Latched" the switching activity will remain off and the V
using the HV start-up generator (as long as there is the mains connected).
3.2.10
PFC HW OVP behavior
Size: 1 bit
Sets the behavior of the PFC OVP.
Available values are:
UM3002 - Rev 1
UM3002
Faults parameters
will remain between 15 V and 17 V
