from a true short. This is done by using the current limit to
control cold filament current in conjunction with the self-
protection circuit of Figure 9. The reduced cold filament
current also extends the life of the filament.
A good guideline is to choose R
SENSE
to set I
SC
at approxi-
mately twice the steady state “on” current of the lamp(s).
t
SHUTDOWN
is then made long enough to guarantee that the
lamp filaments heat and drop out of current limit before the
enable capacitor discharges to the enable low threshold.
For a short circuit, the enable capacitor will continue to
discharge below the threshold, shutting down the top
MOSFET. The LT1158 will then go into the automatic
restart mode described in
Self-Protection with Automatic
Restart
above.
The time constant for an incandescent filament is tens of
milliseconds, which means that t
SHUTDOWN
will have to be
longer than in most other applications. This places in-
creased SOA demands on the MOSFET during a short
circuit, requiring that a larger than normal device be used.
A protected high current lamp driver application is shown
in Figure 18.
