&lt;p&gt;According to the datasheet, the directional current protection detects the voltage between A and C. I just want to confirm, if the LM74800 disconnects pin C from the external MOSFET, will the chip disable the reverse current protection?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
