AP5056
Using SOP8/MSOP8 package
1A Linear Li-Ion Battery Charger
Description
The AP5056 is a complete constant current & constant
voltage linear charger for single cell lithium-ion batteries.
Its SOP/MSOP package and low external component
count make the AP5056 ideally suited for portable
applications. Furthermore, the AP5056 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
AP5056 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 AP5056 automatically enters a low current
state, dropping the battery drain current to less than 2uA.
The AP5056 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.
