This is a fatal problem. For this reason, a complete backflow prevention circuit with low current leakage is necessary. The simplest and most effective measure is configuring a complete backflow prevention circuit using the ideal diode IC.
However, for charger IC that has no built-in backflow prevention function or devices for which a device with a built-in charger IC and a device equipped with a battery are separated, it is necessary to take measures against voltage output to external terminals.
A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.

Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors.
