XC6805
XC6805 is One Cell Li-ion/Li-polymer Linear Charger manufactured by Torex Semiconductor.
DESCRIPTION
The XC6805 is a Constant-Voltage (CV) and Constant-Current (CC) type charging IC for linear charging of single-cell Li-ion batteries and Li-polymer batteries. The basic charging cycle consists of trickle charge mode followed by main charge mode. This IC supports temperature control based on JEITA, making it possible to safely charge Li-ion batteries and Li-polymer batteries by controlling the CV charge voltage and CC charge current according to the temperature. By connecting a resistor to the charge status output pin, it is possible to check the charge condition via the charge status output (CSO) pin voltage. The IC is housed in the small USP-6EL, USP-6B07 package with high heat dissipation, and a charge circuit can be configured using a minimum of external ponents.
