XC6805

XC6805 Series ETR25007-003 One Cell Li-ion/Li-polymer Linear Charger IC with Battery Temperature Detection ■GENERAL 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 components. ■APPLICATIONS z Small Battery z Wearable Device z Fitness Tracker z Hearing Aid z Sm...
