General Description

The AP5057 is a complete constant current & constant

voltage linear charger for single cell lithium-ion batteries.

Its SOP package and low external component count

make the AP5057 ideally suited for portable applications.

Furthermore, the AP5057 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. 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

AP5057 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) is

removed, the AP5057 automatically enters a low current

state, dropping the battery drain current to less than 2uA.

The AP5057 can be put into shutdown mode, reducing

the supply current to 50uA.

Other features include Battery temperature monitor,

under-voltage lockout, automatic recharge and two status

pins to indicate charge and charge termination.
