Optimizing the Load-Switch Function of the DS2715 Battery-Charger IC

Reference Design Disclaimer See the  Important Notice and Disclaimer  covering reference designs and other Maxim resources.



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.
