Unisonic Technologies UB10803
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.| Part No. | UB10803 |

DESCRIPTION
SOP-8 The UTC 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 works completely in a constant-voltage (CV) mode), an EOC indication is displayed through the CHG pins. The UTC UB10803 is protected by thermal regulation technology to prevent the IC from over-heat during charging. Two status indication pins (PPR and CHG), which are both implemented as an open-drain outputs, can be used to drive LEDs or work as logic interface to a microprocessor. When no adapter is attached or when the charger is disabled, the leakage current from battery cell is less than 1uA typically.●
