9.1.3 Power Pin Diodes

The VC5X, VC10X, and BAT pins must have a diode from the top group input to the associated power pin, as shown in Figure 9-2 and Figure 9-3. These diodes limit the excursion of the input voltage above the supply. The diodes should be conventional diodes rather than Schottky type to allow some variation of the supply voltage without loading the cell input. When needed, two diodes may be used in series.
