XS5822

    The XS5822 is a Complete Constant-Current Constant-Voltage Boost Charger for two/Three/Four cell Li-Ion batteries. It’s small footprint and low external component count make XS5822 especially suitable for portable applications. The charge voltage is fixed by R1/R2 and the charge current can be programmed externally with a single resistor. The XS5822 implements BAT over-voltage protection and thermal shutdown. The XS5822 is available in a space saving ESOP-8 Package.
