AP5056 datasheet

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 device 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 IC automatically terminates the charge cycle when the charge current drops to 1/10
th the programmed value after the final float voltage is reached.

Features :

1. No MOSFET, Sense Resistor or Blocking Diode Required
2. Complete Linear Charger in SOP/MSOP Package for single Cell Lithium-Ion Batteries
3. Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate
Without Risk of Overheating
4. Charges Single Cell Li-Ion Batteries Directly from USB Port

Applications :

1. Cellular Telephones, PDAs, MP3 /MP4 Players

2. Charging Docks and Cradles
