Datasheet	A4054A-AiTSemiconductor.pdf

The A4054A is a plete constant current / constant voltage linear charger for single cell Lithium-Ion batteries.

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.

include charge current monitor, under-voltage lockout, automatic recharge and a status pin to indicate charge termination and the presence of an input voltage. A4054A will check the battery voltage first, it will not start charging unless the battery voltage is below the auto-rechrage threshold. The A4054A is available in SOT-25 packages.
