A4054A Datasheet - AiT Semiconductor

A4054A 800mA STANDALONE LINEAR Li-ion BATTERY CHARGER

The A4054A 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 temperatu.

A4054A Features

* 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
