The device can not block a current flow in reverse polarity condition. In order to minimize power dissipation, the
device offers Reversave™ functionality. In reverse polarity condition the channel will be switched on provided a
sufficient gate to source voltage is generated

ground. This can be achieved e.g. by using a small signal diode D in parallel to the input switch or by using a small
signal MOSFET driver. For reverse battery voltages higher then
recommended. The overall current through
Note: No protection mechanism is active during reverse polarity. The IC logic is not functional.
