UB10803 ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER

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 discha.
