Single Cell Li-Ion / Li-Polymer Charger IC
THE XC6805 SERIES IS NOW END OF LIFE AND SHOULD NOT BE USED FOR NEW DESIGNS
We recommend the XC6808 series for all new projects.
The XC6805 is a Constant-Voltage (CV) and Constant-Current (CC) type charging IC for linear charging of single-cell Li-ion and Li-polymer batteries. The basic charging cycle consists of trickle charge mode followed by main charge mode.
An LED can be connected to the charge status output pin to allow confirmation of charging by LED illumination. The IC is housed in the small USP-6EL package with high heat dissipation, and a charge circuit can be configured using a minimum of external components.
These IC also support temperature control based on JEITA, making it possible to safely charge Li-ion batteries by controlling the CV charge voltage and CC charge current according to the temperature.
