Single-Cell Lithium-Ion (Li-ion) Battery Charger
AN73468 explains a single-cell Lithium-Ion (Li-ion) battery charger implementation using PSoC 3. Two types of implementations-linear and switching type are supported. An attached PSoC Creator project, which includes a charge display tool, demonstrates Li-ion battery charging.
Li-ion batteries are used in a wide range of systems such as cameras, cell phones, electric shavers, and toys. The charging circuit for the batteries can either be an integral part of the system (online charging) or an external plug-in circuit (offline charging). With its wide range of devices, PSoC 3 offers a cost-effective solution in both segments. And with its configurable digital and analog features, PSoC 3 enables implementation of other critical tasks required in the system.
