This protection requires a Resistor in the GND path. The recommended GND resistor is 150 W, but a variety of resistor values can be chosen for this purpose. The graph below shows the considerations and constraints for selection of the GND resistor. Figure 2 shows the power dissipation in the GND resistor during a 32 V reverse battery event on the left axis, while the right axis shows the voltage drop across the GND resistor while in normal operation. The far right side of the graph is grayed out to indicate that the voltage drop across the resistor is too high, and the part will not be able to turn on with a standard 5 V on the input pin. Selection of the optimal GND resistor requires balancing the power dissipation considerations while in a reverse battery event, with the turn on capability of the input signal during normal operation.
