16
) Short circuit is a failure mode. The device is not designed to operate continuously into a short circuit by
permanent resetting the short circuit latch function. The lifetime will be reduced under such condition.
17
)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
is clamped to V
- V
at inductive load switch off.
18
)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.
