EUP8060X
1A Li-Ion/Polymer Charger IC with Thermal Regulation and OVP
DESCRIPTION
The EUP8060X series are highly integrated single cell Li-Ion/Polymer battery charger IC designed for handheld devices. The EUP8060X integrates internal power FET, current sensor, charge status, reverse current protection and overvoltage protection (OVP) in a single monolithic devices. When AC-adapter is applied, an external resistor sets the magnitude of the charge current, which may be programmed up to 1A. Thermal feedback also regulates the charge current to limit the die temperature when fast charging or while exposed to high ambient temperature. The EUP8060X charges the battery in three phases: conditioning, constant current, and constant voltage. Charge is terminated based on minimum current.
