BL4054 Datasheet (Shanghai Belling) - 800mA Standalone Linear Li-Ion Battery Charger

BL4054, 800mA Standalone Linear Li-Ion Battery Charger

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
