In case of reverse polarity, the intrinsic body diode causes power dissipation. The current in this intrinsic body
diode is limited by the load itself. Additionally, the current into the ground path and the logical pins has to be limited
to the maximum current described in

In case of overload, or short circuit to ground, the BTS4160DGA offers several protections mechanisms.
6.5.1
At first step, the instantaneous power in the switch is maintained to a safe level by limiting the current to the
maximum current allowed in the switch
the current flowing in the DMOS. At thermal shutdown, the device turns OFF and cools down. A restart mechanism
is used, after cooling down, the device restarts and limits the current to
the current limitation as a function of time.
