Description
bq2002/F NiCd/NiMH Fast-Charge Management ICs .
The bq2002 and bq2002/F Fast-Charge ICs are low-cost CMOS battery-charge controllers providing reliable charge termination for both NiCd and NiMH batt.
Features
* ➤ Fast charge of nickel cadmium or nickel-metal hydride batteries
➤ Direct LED output displays charge status
➤ Fast-charge termination by -∆V, maximum voltage, maximum temperature, and maximum time
➤ Internal band-gap voltage reference
➤ Optional top-off charge
➤ Selectable pulse trickle charge rate
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 batte
