DESCRIPTION
FEATURES
The A4053 is a complete constant current & constant
voltage linear charger for single cell lithium-ion
batteries. Its P-MSOP package and low external
component count make the A4053 ideally suited for
portable applications. Furthermore, the A4053 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
A4053 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 A4053 automatically enters a low
current state, dropping the battery drain current to
less than 2uA. The A4053 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.
The A4053 is available in P-MSOP8 Package
