General Description
The bq2002C Fast-Charge IC is alow cost CMOS battery-char ge controller providingreliable charge termination for bothNiCd and NiMHbattery applications. Controlling a current-limited or constant-current supplyallows the bq2002C to be thebasis for acost effectivestand-alone or system-inte grated charger. Thebq2002Cinte grates fast charge withpulsed-trickle control in a single IC for charging one or more NiCd orNiMHbatterycells.

Features
➤ Fast charge of nickel cadmium
   or nickel-metal hydride batteries
