XC6802 Series
ETR2501-006
800mA Single Cell Li-ion Battery Linear Charger IC
■ GENERAL DESCRIPTION
The XC6802 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC6802
includes 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 R SEN 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.
