Protection Pin - Lx1692

for more than 256 clock counts, the fault latch is set, and the device shuts down.

Detected via the OVNS and ISNS pins if current doesn't flow after striking. lx1692 protection pin

At its core, the LX1692 is a sophisticated PWM controller. It drives the MOSFETs that generate high voltage. However, high voltage comes with high risk. If a transformer arcs, a capacitor shorts, or a lamp disconnects, the results can be catastrophic—not just for the light, but for the PCB traces and the silicon driver itself. for more than 256 clock counts, the fault
