OVERLOAD PROTECTION CHARACTERISTICS
With adequate protection supply
voltage TOPFET detects when one
of the overload thresholds is
exceeded.
SYMBOL

Provided there is adequate input
series resistance it switches off
and remains latched off until reset
by the protection supply pin.

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.
2
At the appropriate nominal protection supply voltage for each type. Refer to QUICK REFERENCE DATA.
3
The over temperature protection feature requires a minimum on-state drain source voltage for correct operation. The specified minimum I
D
ensures this condition.
4
During overload condition. Refer also to OVERLOAD PROTECTION LIMITING VALUES and CHARACTERISTICS.
5
The supply voltage below which the overload protection circuits will be reset.
6
The reverse diode of this type is not intended for applications requiring fast reverse recovery.
