Reverse voltage protection

This chip did not work well for our application. Since it trying to keep a 30mV drop between IN and OUT it is regulating the gate voltage to increase the resistance of the mosfets when the load current is low, this then results in complete cutoffs when we switch the motors from 100% to 0% since we go from a high current load to a low one.
Did also try with N chl mosfets that have a higher Rdson to increase the voltage drop but again when switching the load its turn off the fets.
