Torex Semiconductor XC680x One Cell Li-ion/Li-poly Linear Charger ICs are Constant Voltage (CV) and Constant Current (CC) charging ICs. These ICs are ideal for linear charging of single-cell Li-ion and Li-polymer batteries. The charging cycle consists of a trickle charge mode followed by a main charge mode. The ICs support temperature control based on JEITA to safely charge Li-ion batteries and Li-polymer batteries. This is achieved by controlling the CV charge voltage and CC charge current according to the temperature. Checking the charge condition via the charge status output (CSO) pin voltage is possible by connecting a resistor to the charge status output pin. Torex Semiconductor XC680x ICs are housed in a SOP-8FD or USP-6EL package with high heat dissipation. A charge circuit can be configured using a minimum of external components.
