GENERAL DESCRIPTION
HE4056 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 n 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 HE4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.鹿晗原名
When the input supply (wall adapter or USB supply) is removed the HE4056 automatically enters a low current state dropping the battery drain current to less than
2μ A.The HE4056 can be put into shutdown mode reducing the supply current to 55μA.
Other features include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.

Description of the Principle
The HE4056 is a complete CC/CV linear charger for single cell lithium-ion batteries. CC/CV to charger batter by internal MOSFET .It can deliver up to 1.1A of charge current .No blocking diode or external current n resistor is required. HE4056 include two Open-Drain charge status Pins: Charge status indicator CHRG and battery failure status output STDBY.
The internal thermal regulation circuit reduces the programmed charge current if the die temperature attempts to ri
