a solenoid having an inductance of 73.8 mH and a resistance
of 95
to flow with the MC3392 in the ON state. The resulting current
value is within the normal load current operating region and
will not produce a fault. Load current is paramount in any
design using the MC3392 and must be less than I SC for

acceptable operation. If the load current is greater than I SC , a
current limit fault state will exist. Operation in this state is not
destructive as the device will turn off if the Junction
Temperature (T J ) rises above 150 C. When the Junction
Temperature cools below 150 C the device will again
turn–on, with a repeat of the cycle. Careful design to
acceptable load current limits should be insured for
satisfactory operation of an application.
