The second protection lead, SD, is used for both
unlatched shutdown and automatic restart functions.
The SD lead would normally be connected to an
external circuit which senses the presence of the
lamp (or lamps), as shown in Figure 12.

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 into the fixture, the SD lead would be pulled
back to near the ground potential. Under these
