data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.

This output clamp can be "switched off" by using an additional diode at the IS-Pin (see page 8). If the diode
is used, V

)
The reverse load current through the intrinsic drain-source diode has to be limited by the connected load (as
it is done with all polarity symmetric loads). Note that under off-conditions (I
IN
= I
IS
= 0) the power transistor
is not activated. This results in raised power dissipation due to the higher voltage drop across the intrinsic
drain-source diode. The temperature protection is not active during reverse current operation! Increasing
reverse battery voltage capability is simply possible as described on page 9.
