XC6804 Datasheet | Torex Semiconductor

DESCRIPTION The XC6804 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 SOP-8FD or USP-6EL package with high heat dissipation, and a charge circuit can be configured using a minimum of external ponents. - APPLICATIONS - Health care devices - Power banks - Portable audio players - Bluetooth headsets - Portable navigation devices - Digital still cameras - FEATURES JEITA conforming Thermistor Detect Function Built-in Operating Voltage Range : 4.5V ~ 6.0V Supply Current : TYP. 100μA CC Charge Current : 200m A ~ 800m A Can be set by external resistance CV Charge Voltage : 4.2V, 4.05V (at high temperature) Internally fixed Protection Circuit : Thermistor detection function Safety timer function UVLO (Under Voltage Lockout) Thermal shutdown (Auto recovery) Dropout voltage monitor function Charging over-voltage monitor function Charging over-current monitor function Recharge function (XC6804xx E) Operating Ambient Temperature : -40°C ~ 85°C Packages : SOP-8FD, USP-6EL Environmentally Friendly : EU Ro HS pliant, Pb Free - TYPICAL APPLICATION CIRCUIT 4.5 ～6 V CIN 1µF CSO ISET BAT THIN...
