XC6802
XC6802 is 1 Cell Li-ion Battery Linear Charger manufactured by Torex Semiconductor.
DESCRIPTION
The XC6802 series is a constant-current/constant-voltage linear charger IC for single cell Lithium-ion and Lithium polymer batteries.The XC6802 includes a reference voltage source, battery voltage monitor, driver transistor, constantcurrent/constant-voltage charge circuit, overheat protection circuit and phase pensation circuit. The battery charge termination voltage is internally set to 4.2V±0.7% and the trickle charge voltage and accuracy is 2.9V±3%. In trickle charge mode, a safe Lithium-ion and Lithium polymer battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery. With an external RSEN resistor, the charge current can be set freely up to 800m A (MAX.), therefore, the series is ideal for various battery charge applications.The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state while connecting with an external LED.
