Product Summary

The SC802 and SC802A are fully integrated, single cell,constant-current/constant-voltage Lithium-Ion/LithiumPolymer battery chargers. With an integrated timer and complete charge control algorithm, the devices are opti- mized for stand-alone charger applications. They provide for programmable pre-charge, fast-charge, and termina- tion current settings. The devices can be programmed to terminate the charge cycle based on the output current or the time-out of the programmable timer. The fast-charge current is typically set with an external resistor but can be modified with the analog fast-charge input to allow a Power Management Controller to control the fast-charge current setting via DAC.
