In case the DC bus decreases too far and the lamp extinguishes, the VCC voltage will
go below VCCUV- (10.5V, typical) and the ignition/preheat ramp will be reset to re-
ignite the lamp reliably.

Lamp Removal
When the lamp is removed, the IRS2530D uses the Crest Factor Over-current
Protection to enter the Fault mode and shut down. During lamp removal, the output
stage will transition to a series-LC configuration, and the frequency will move towards
resonance until the inductor saturates. The IRS2530D uses the VS-sensing circuitry
and the RDSon of the low-side half-bridge MOSFET to measure the MOSFET current
for detecting an over-current fault. Should the peak current exceed the average current
by a factor of 5.5 (CF>5.5) during the on-time of LO, the IRS2530D will enter Fault
Mode, where the half-bridge is off. Performing crest factor measurement provides a
relative current measurement that cancels temperature and/or tolerance variations of
the RDSon of the low-side half-bridge MOSFET.
Figure 10.3 shows the voltage across the lamp and the VS voltage when the lower
filament of the lamp is removed. Figure 10.4 shows these voltages when the upper
filament of the lamp is removed. In both cases, the IRS2530D will enter the Fault Mode
and shut down after detecting that the crest factor exceeds 5 during the on-time of LO.
Figure 10.5 shows the VS pin, inductor current, and voltage across lamp when the
inductor saturates and the ballast shuts down.
