When the boot switch is activated a

When the boot switch is activated after the system is running, the voltage for cell 1 and cell 2 may bealtered by the current drawn through the cell input filter resistor Rc. Typically the switch ON time is low,and the cell voltages use some filtering, so this changed voltage may have little or no impact on thesystem. If the user were to hold the switch or the button were to stick, a noticeable system effect may beobserved, depending on the resistor values used. Where the voltage change is objectionable, the switchcould be fed directly from the cell 1 voltage. This eliminates the measured voltage change due to switchactivation, however holding the switch loads the cell.
