About this manual

The bq2002E and bq2002G Fast-Charge ICs are low-cost CMOS battery-charge controllers designed for nickel cadmium and nickel-metal hydride battery applications. They control current-limited or constant-current supplies to serve as stand-alone or system-integrated chargers. The devices integrate fast charge with optional top-off and pulsed-trickle control in a single IC for charging one or more battery cells.
