General Description

The BL4054/BL4054B is a complete 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.
