UNISONIC TECHNOLOGIES CO., LTD UB10803 Preliminary CMOS IC ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER - DESCRIPTION SOP-8 The UTC UB10803 is a fully-integrated single-cell Li-ion/Polymer battery charger. The device operates without external FET and blocking diode, and employs a constant-current constant-voltage (CC/CV) charging profile. The fast-charge and end-of-charge (EOC) currents are programmable with independent external resistors. When the battery is deeply discharged to lower than 2.75V, the charger firstly pre-charges the battery with typically 20% of the programmable fast-charge current. When the charge current is reduced to the programmed EOC current level (almost...
