2.6
In order to prevent a malfunction in the area of Capacitive Load (see Figure 24) during Run Mode due
to certain deviations from the normal load (e.g. harmed lamp, sudden break of the lamp tube …), the
IC has three integrated thresholds – sensed only via the LSCS (pin 1). The controller distinguish
between two different states of capacitive load, the detection of working without load (idling detection,
CapLoad 1) and working with short over current (CapLoad 2). This state (CapLoad 2) is affecting an
operation below the resonance in the capacitive load area (Figure 24). In both cases, 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 status of the fault and restarts after the fault disappears e.g. in case of
inserting a new lamp.
