The XC6802 series is a single cell lithium ion battery constant current/constant voltage linear charger IC, including a reference voltage source, battery voltage monitor, driver transistor, constant current/constant voltage charge circuit, over heat protection circuit, phase compensation 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 charge to a battery is possible because approximately 1/10 out of setting charge current is supplied to the battery. With an external RSEN resistor, the charge current can be set freely up to 800mA (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.
