The DS2715 is unique compared to other charging ICs in that it provides a charging and discharging path to battery cells through a single transistor. This functionality, combined with its 10-cell charging capacity, makes it a very popular charging solution for many types of battery-powered devices. Explaining exactly how the DS2715 controls the regulation transistor, this application note describes circuit adjustments that designers can make to optimize their DS2715 application. First, it details a typical application circuit for a 3-cell battery pack. Then, it presents two alternate circuits: an improved circuit for applications in which the DS2715 is connected to loads that operate noncontinuously, and a circuit for powering the load directly from batteries.
