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.
The current leakage of the ideal diode is about 0.1 μA even at high temperatures, however, for SBD, leakage current of 100 μA or more is flowing. This paper explained that using the ideal diode IC could easily configure the complete backflow prevention circuit.
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.
Back-to-back FETs to Prevent Reverse Current This method is the least common way of implementing reverse current but is still extremely effective, as it eliminates the body diode of the MOSFET. This method ties the bulk of the MOSFET to GND, eliminating the connection to the source that was causing the parasitic body diode.
