2.8.2 Deactivation of the Filament Detection
In order to deactivate the filament detection of the low or high side filament, set the RES pin 12 or the
LVS1 / LVS2 pin 13 / 14 to GND. In that case, the IC starts up into normal operation without checking
the filaments e.g. when using an equivalent lamp resistive load instead of a load.
Figure 34 shows the deactivation of the low and high side filament via set the RES pin 12 to GND.
Figure 35 shows the deactivation of the high side filament detection via set the LVS1 or LVS2 pin to
GND.
Note
In case using just one path of a ballast design (single or dual lamp in series) one of the not used LVS
pins has to be set to GND.
