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) This output clamp can be "switched off" by using an additional diode at the IS-Pin (see page 8). If the diode
is used, VOUT is clamped to Vbb- VON(CL) 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 (IIN = IIS = 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.

the input switch, by using a MOSFET input switch or by
proper adjusting the current through RIS and RV.

The device is specified for inverse load current

is not available during this kind of operation (IIS = 0).
With IIN = 0 (e.g. input open) only the intrinsic drain
source diode is conducting resulting in considerably
increased power dissipation. If the device is switched

much lower value RON(INV) * I2 (specifications see page
