SC805 Miniature Integrated High Current Lithium-Ion Battery Charger

The SC805 is a fully integrated, single cell, constant-current (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 Controller (PMIC). The SC805 has a pre-charge function for trickle charging deeply discharged .
