The bq2002 and bq2002/F Fast-Charge 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 bq2002/F to be the basis for a cost-effective stand-alone or system-integrated charger. The bq2002/F 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. Fast charge is initiated on application of the charging supply or Battery
replacement. For safety, fast charge is inhibited if the Battery
temperature and voltage are outside configured limits.
