The CXLB7201F is a complete constant current/constant voltage linear charger for single cell lithium-ion batteries.
Its package and low external component count make the CXLB7201F ideally suited for portable applications.
Furthermore, the CXLB7201F is specifically designed to work within USB power specifications.
No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture.
The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor.
The CXLB7201F automatically terminates the charge cycle when the charge current drops to 1/10th the programmed
value after the final float voltage is reached.
