The circuit in Figure 6 will provide adapter current limit-
ing 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.
