For operation at voltages higher then |16V| please see required schematic on page 10.  
Permanent Inverse operation results eventually in a current flow via the intrinsic diode of the power DMOS.  
In this case the device switches on with a time delay td(inv) after the transition from inverse to forward mode.

Short Circuit is detected at the following condition: VON > 3.5V (typ.) . See also page 11.  
Low ohmic short to Vbb may reduce the output current IL and therefore also the sense current IIS.

To minimise power dissipation at reverse battery  
operation, the overall current into the IN and IS pin  
should be about 80mA. The current can be provided by  
using a small signal diode D in parallel to the input

adjusting the current through R  
IS.  
Since the current via R generates additional heat in  
bb  
the device, this has to be taken into account in the  
overall thermal consideration.

The device can be operated in inverse load current  
mode (VOUT > Vbb > 0V). The current sense feature is  
not available during this kind of operation (IIS = 0). In  
case of inverse operation the intrinsic drain source  
diode is eventually conducting resulting in considerably  
increased power dissipation.  
The transition from inverse to forward mode can result  
in a delayed switch on.  
Note: Temperature protection during inverse load  
current operation is not possible!
