AVR458: Charging Li-Ion Batteries with BC100

This application note is based on the ATAVRBC100 Battery Charger reference design (BC100) and focuses on how to use the reference design to charge Lithium-Ion (Li-Ion) batteries. The firmware is written entirely in C language (using IAR® Systems Embedded Workbench) and is easy to port to other AVR® microcontrollers. This application is based on the ATtiny861 microcontroller but it is possible to migrate the design to other AVR microcontrollers, such as pin-compatible devices ATtiny261 and ATtiny461. Low pin count devices such as ATtiny25/45/85 can also be used, but with reduced functionality.
