General Description

The A4055 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.

Key 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. The A4055 is available in SOT-25 Package.
