1
The short circuit load protection is able to save the device providing the instantaneous on-state dissipation is less than the limiting value for
P
DSM
, which is always the case when V
DS
is less than V
DSP
maximum. Refer to OVERLOAD PROTECTION LIMITING VALUES.
2
The over temperature protection feature requires a minimum on-state drain source voltage for correct operation. The specified minimum I
D
ensures this condition.
3
The input voltage below which the overload protection circuits will be reset.
