Functional Description
2.5.2 Detection of End-of-Life (EOL2) – Rectifier Effect
The rectifier effect (EOL2) is detected by measuring the positive and negative DC level of the lamp
voltage via a current fed into the LVS pin (Figure 23). This current is fed into the LVS pins (LVS1 for
single lamp and LVS2 for multi lamp applications) via Network R41, R42 and R43 (see Figure 3). If the
sensed DC current exceeds ± 42 µA (Figure 23 LVSDC Current) for longer than 2500 ms, the status of
end-of-life (EOL2) is detected. The EOL2 fault results in a latched power down mode (after trying a
single restart) the controller is continuously monitoring. Only the insert of a new lamp resets the status
of the IC.
