UB10803 Product details

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 c.
