The BSP742R is high side power switch with integrated vertical power
FET, providing embedded protection and diagnostic functions.

The reverse load current through the intrinsic drain-source diode has
to be limited by the connected load. Power dissipation is higher compared
to normal operating conditions due to the voltage drop across the drain-
source diode. The temperature protection is not active during reverse
current protection.
