AF4056E 1.1A Lithium Ion Battery Linear Charger GENERAL DESCRIPTION AF4056E is a complete CC/CV linear charger for single cell lithium-ion batteries. It 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 P-MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature .The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The AF4056E automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
