CE3213

1A SINGLE-CHIP Li-Ion/Li-Pol CHARGE MANAGEMENT IC CE3213 Series „ INTRODUCTION: The CE3213 series are highly integrated Li-Ion and Li-Pol linear charger management devices, targeted at space limited portable applications. Furthermore, the CE3213 is specifically designed to work within USB power specifications. The CE3213 series offers a variety of safety features and functions, while still implementing a complete charging system in a small package. The battery is charged in three phases: conditioning, constant or thermally regulated current, and constant voltage. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. Charge is terminated based on minimum current. The CE3213 automatically restarts the charge if the battery voltage falls below an internal threshold; low-power consumption sleep mode is automatically set when the external input supply (wall adapter or USB supply) is removed.
