FIGURE 9.
4-Cell Battery Circuit
Four Cell Application
Figure 9 shows a method for using the Si9730 in a 4-cell
application. Basically, this is two complete 2-cell circuits
stacked in series. Each half of the complete circuit monitors its
own 2-cell portion of the battery, and opens its own MOSFET
switch under any of the appropriate conditions. Observe that
the total percent power loss in this circuit is identical to that in
the 2-cell application; although there are now two sets of
MOSFETs in series, there is also double the battery voltage,
and so total efficiency is the same.
One novel feature of this 4-cell circuit is the increase in the
size of the bypass capacitors. Each half of the circuit retains
its own output cap, to reduce noise seen by the circuit. Since
the two halves interact with each other (when one opens its
switch, the other one is also opened), there can be additional
noise, which must be rejected for proper operation. The
capacitors have been increased to 100 μF for this reason;
remember that they must be rated to take the full maximum
voltage rating of the charger, not half of it, since if one switch
is closed and the other open, the charger (minus two cells’
voltage drop, which might be zero) is applied across the other
capacitor.
A second addition on this circuit is the (optional) two zeners,
one each for each Si9730, placed from V
