XC6802 Series ETR25001-011 800mA 1 Cell Li-ion and Li-Po Battery Linear Charger IC with Constant-Current/Constant-Voltage ■GENERAL 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 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 Lithium-ion and Lithium polymer battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery.
