Miniature Integrated High Current Lithium-Ion Battery Charger

The SC805 is a fully integrated, single cell, constant-cur- rent (CC)/constant-voltage (CV) Lithium-Ion battery charger in a tiny 3x3 mm thermally enhanced lead free MLP package. The SC805 CAN operate as a stand-alone charger or in conjunction with a Power Management Con- troller (PMIC). The SC805 has a pre-charge function for trickle charging deeply discharged batteries. The fast charge current is enabled automatically when the battery voltage reaches the required threshold. When the battery reaches the constant voltage or CV portion of the charge curve the SC805 switches to CV regulation mode. In this mode the output current decays as the battery charges unti the termination current is reached and the SC805 sig- nals the charge cycle is complete. The SC805 CAN be configured to continue charging for a predetermined time before turning off, or to turn off immediately upon termi- nation. After turning off its output, The SC805 enters monitor mode. If the battery voltage drops by 100mV from the CV voltage a new charge cycle will begin. The Timer function also protects against charging faulty bat- teries by turning off if the pre-charge time exceeds 1/4 of the total programmed charge duration. By Semtech Corporation
