Introduction: 1 Cell LiPo / Li-ion Battery Charger CC&CV
Hi there. I would like to show you guys the smallest and simplest single cell Li-Ion & LiPo battery charger pack with all the necessary functions. Detail as follow. Description from its spec. 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 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.
