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. 16) 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! To reduce the power dissipation at the integrated Rbb resistor an input resistor is recommended as described on page 9.

The current sense feature 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 on (VIN = 0), this power dissipation is decreased to the much lower value RON(INV) * I2 (specifications see page 4).
