4056E 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 4056E automatically terminates the charge cycle when the charge current drops to 1/10th


the programmed value after the final float voltage is reached.


When the input supply (wall adapter or USB supply)isremovedthe4056Eautomatically


enters a low current state dropping the battery drain current to less than 2μA.

Other features include Battery temperature monitor, under-voltage lockout, automatic


recharge and two status pins to indicate charge and charge termination.
