OPERATIOU
Programming Charge Termination
The LTC4061 can terminate a charge cycle using one of
several methods, allowing the designer considerable flex-
ibility in choosing an ideal charge termination algorithm.
Table 1 shows a brief description of the different termina-
tion methods and their behaviors.
