A second threshold detects severe deviations such as rectangular shapes of voltage during operation below
resonance (CapLoad2). Then the inverter is turned off as soon as these conditions last longer than 610μs and the
IC changes over into fault mode. The evaluation of the failure condition is done by an up and down counter which
samples the status every 40μs.
CapLoad1 is sensed in the moment when low-side Gate drive is turned on. If the voltage level at pin RES is above
the V
REScap
threshold (typ. 0,24V) related to the level V
RESLLV
, conditions of CapLoad1 are assumed.
CapLoad2 is sensed in the moment when the high-side Gate drive is turned on. If the voltage level at pin RES is
below the V
REScap
threshold related to the level V
RESLLV
, conditions of CapLoad2 are assumed. As the reference
level V
RESLLV
D10 limits voltage transients at pin RES that can occur during removal of the lamp in run mode.

Interruption of Operation and Restart after Lamp Removal
In the event of a failing operation the fault latch is set after the specified reaction time (e.g. 500ms at EOL2). Then
the Gate drives are shut down immediately, the control functions are disabled and the current consumption is
reduced to a level of 150μA (typically). Vcc is clamped by internal zener diode to max 17,5V at 2mA. So the
internal zener diode is only designed to limit Vcc when fed from the start-up current, but not from the charge pump
supply! There is a current limitation at the internal zener diode function (max 5mA at Vcc= 17,5V) in order to avoid
conflicts with the clamping level of the external zener diode.
The capacitor at pin RES is discharged and charged during 32 cycles in order to generate a delay of several 10ms.
The delay is implemented for avoiding malfunctions in detecting the lamp removal due to voltage transients that
can occur after shut down. The reset of the fault latch happens after exceeding the 1,6V threshold at pin RES and
enabling the IC after lamp removal and subsequent decreasing voltage level at pin RES below the 1,3V threshold.
