The circuit in Figure 6 will provide adapter current limiting
to ensure that the battery charger never overloads the
adapter. In addition, it adjusts charging current to a lower
value if other system power increases to the point where
the adapter would be overloaded. This allows the LT1512
to charge the battery at the maximum possible rate without
concern about varying system power levels. The LM301 op
amp used here is unusual in that it can operate with its
inputs at a voltage equal to the positive supply voltage.
