The bq2002E and bq2002G FastCharge ICs are low-cost CMOS battery-charge controllers providing reliable charge termination for both NiCd and NiMH battery applications. Controlling a current-limited or constant-current supply allows the bq2002E/G to be the basis for a costeffective stand-alone or system-integrated charger. The bq2002E/G integrates fast charge with optional top-off and pulsed- trickle control in a single IC for charging one or more NiCd or NiMH battery cells.
