DESCRIPTION
The XR4056 and XR4056A are complete constant-current/ constant-voltage Li-Ion and LiPolymer linear chargers targeted at spaced limited portable applications. Furthermore, the XR4056 and XR4056A are specifically designedto work within USB power specifications.
No external sense resistor is needed, and no blocking diode is required due to the internal 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 (XR4056) or 4.35V (XR4056A), and the charge current can be programmable externally.
The device terminates the charge cycle when the charge current drops to 1/10 of the presetting value after the final float voltage is reached.When the input supply is removed, the
XR4056/XR4056A enters a low current state,dropping the battery drain current to less than 1μA.The XR4056/XR4056A can be put into shutdown mode, reducing the supply current to 75μA during adaptor is present. The other features of XR4056/XR4056A include external battery temperature monitor, two open-drain outputs indicator, and automatic recharge function.
The XR4056/XR4056A guarantees robustness with input and battery reverse connection protection, input over voltage protection, thermal shutdown and under voltage lockout.
