IIS=0 by IIN =0 (e.g. during deenergizing of inductive loads):
16) Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not
designed for continuous repetitive operation.
17 ) Short circuit is a failure mode. The device is not designed to operate continuously into a short circuit. The
lifetime will be reduced under such conditions.

)
This output clamp can be "switched off" by using an additional diode at the IS-Pin (see page 7). If the diode
is used, VOUT is clamped to Vbb- VON(CL) at inductive load switch off.
The reverse load current through the intrinsic drain-source diode has to be limited by the connected load (as
19
)
it is done with all polarity symmetric loads). Note that under off-conditions (I =I =0) the power transistor
IN IS
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 8.

)
If VON is higher, the sense current is no longer proportional to the load current due to sense current
saturation, see IIS,lim
.
