Driven by the need for untethered mobility and
ease of use, many systems rely on rechargeable batteries as their primary power source. The battery
charger is typically implemented using a fixed-function
IC to control the charging current/voltage profile.

The C8051F300 family provides a flexible alternative
to fixed-function linear battery chargers. This application note discusses how to use the C8051F300 device in Li-Ion battery charger applications. The Li-Ion
charging algorithms can be easily adapted to other battery chemistries.
