Lamp Presence and End-of-Life Detection
The second protection pin, SD, is used for both shutdown
and end-of-life detection. The SD pin would normally be con-
nected to an external circuit that senses the presence of the
lamp(s) and the voltage appearing across the lamp(s). An
example circuit for a single lamp is shown in Figure 14. During
all modes of operation if the SD pin exceeds 5.1V (approxi-
mately 150mV of hysterisis is included to increase noise
immunity), signaling either a lamp fault or lamp removal, the
oscillator is disabled, both gate driver outputs are pulled low,
and the chip is put into the micropower mode. Since a lamp
fault would normally lead to a lamp exchange, when a new
lamp is inserted in the fixture, the SD pin would be pulled
back to near ground potential. Under these conditions a
reset signal would restart the chip from the beginning of the
control sequence, as shown in the timing diagram in Figure
15.
Thus, for a lamp removal and replacement, the ballast
automatically restarts the lamp in the proper man
ner.
In the Run mode there are two additional thresholds
enabled on the SD pin: 1V and 3V. These thresholds form a
window and during normal lamp running the voltage
appearing at the SD pin is maintained within these two levels.
As a lamp nears its end-of-life, its running voltage will increase
and the signal applied to the SD pin detects this by exceeding
the window threshold width. The oscillator is disabled, both
gate driver outputs are pulled low, and the chip is put into the
micropower mode.
