Product Summary

The BQ2002E and bq2002G Fast-Charge ICs are low-cost CMOS bat-tery-charge controllers providing reli-able charge termination for both NiCdand NiMH battery applications. Con-trolling a current-limited or con-stant-current supply allows thebq2002E/G to be the basis for a cost-effective stand-alone or system-inte-grated charger. The bq2002E/G inte-grates fast charge with optional top-offand pulsed- trickle control in a singleIC for charging one or more NiCd orNiMH battery cells.
