GENERAL DESCRIPTION
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. The LP28055 automatically terminates the charge cycle when the charge current drops to 1/10 setting current value after the final float voltage is reached. When the input supply is removed, the LP28055 automatically enters a low current state, dropping the battery drain current to less than < 1µA. Other features include charge current m
