This pin allows for Programmable Time-Out Protection . By connecting an external capacitor, you can set the maximum "strike interval" duration. If the lamp fails to ignite within this time, the IC shuts down the outputs to prevent component damage.
Bypassing the protection pin should only be done for testing. Running an inverter without active protection can lead to transformer overheating or fire if a genuine short circuit exists. Technical Specifications Summary lx1692 protection pin
