The XC6801A421ER-G series is a constant-current/constant-voltage linear charger IC for single cell Lithium-ion and Lithium polymer batteries.The battery charge termination voltage is internally set to 4.2V ±0.7% and the trickle charge voltage and accuracy is 2.9V ±3.0%. 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. As it is possible to select a USB charge current of either 100mA (MAX.) or 500mA (MAX.) by using the Lim pin, the series is ideal for applications where the charge is from USB power. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state via connection to an external LED. 9icnet Electronics is an authorized Torex distributor.
