OVERLOAD PROTECTION CHARACTERISTICS
TOPFET switches off when one of the overload thresholds is reached. It remains latched off until reset by the input.
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
2 The over temperature protection feature requires a minimum on-state drain source voltage for correct operation. The specified minimum I
