Thermlsches Abschalten:
Die eingebaute thermische Begrenzerschal-
tung ergibt tolgende Vorteile:
l, Eine dauernde Uberlastung des Ausganges
oder eine Erh0hung der zultissigen oberen
Umgebungstemperatur kann einfach ver-
hindert warden.
2. Die K0hlung kann gegeniiber konventionel-
len Schaltungen mit einem kleineren Sicher-
heitstaktor agsgelegt warden. Bei elnar
thermlschen Uberlastung wird der Schalt-
kreis nicht infolge einer zu hohan Sperr-
schichttemperatur zerstbrt. denn es wird
aussChlie8liCtt Pa (und somit Ptot) und fs
reduzlert (siehe Fig. 11).

Thermal shut-down
The presence of a thermal limiting clrcult offers
the following advantages:
1. An overload on the output (even If It Is
permanent), or an above-llmlt ambient tem-
perature can be easily supported.
2. The heat sink can have a smaller factor of
safety compared with that of a conventional
circuit. There Is no device damage In the
case of too high a function temperature:
all that happens is that Po (and therefor P100
and fs are reduced (fig. If).
