2.6
In order to prevent a malfunction in the area of Capacitive Load (see Figure 23) during Run Mode due
to certain deviations from the normal load (e.g. harmed lamp, sudden break of the lamp tube …), the
IC has two integrated thresholds – sensed only via the LSCS (pin 1). The controller detects working
with short over current (CapLoad 2). This state (CapLoad 2) is affecting an operation below the
resonance in the capacitive load area (Figure 23). In this case the IC results in a latched power down
mode after a single restart. After latching the power down mode, the controller is continuously
monitoring the input voltage and lamp filaments and restarts after interrupting the input voltage or
inserting a new lamp.
