BQ2002FPN

Battery Chargers Overview

The BQ2002FPN is a low-cost CMOS battery-charge controller manufactured by Texas Instruments. It provides reliable charge termination for both Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries. The device supports fast-charge management and includes direct LED output capabilities to display charge status. It utilizes negative delta voltage (-ΔV) detection for fast-charge termination, ensuring efficient and safe charging cycles for compatible battery chemistries.

Battery Chargers Feature Summary

• Provides reliable charge termination for NiCd and NiMH battery types
• Supports fast-charge management with direct LED output for status indication
• Utilizes negative delta voltage detection for accurate charge completion

Battery Chargers Applications

• Fast-charging systems for Nickel-Cadmium batteries
• Fast-charging systems for Nickel-Metal Hydride batteries
• Battery management circuits requiring visual charge status feedback

Battery Chargers Procurement Notes

Verify the specific suffix 'FPN' against the manufacturer's current documentation to confirm package type and temperature range specifications. Note that the BQ2002 family has reached End-of-Life status as indicated in public product change notifications; ensure availability of alternative sources or replacement components before procurement planning.

Battery Chargers Selection Notes

Select this component when designing cost-sensitive chargers for NiCd or NiMH cells requiring simple -ΔV termination logic. Ensure the application does not require advanced features like thermal regulation or trickle charge adjustments not covered by this basic controller. Confirm compatibility with the target battery chemistry's voltage characteristics.

Battery Chargers Part Context

The BQ2002FPN belongs to the BQ2002 series of battery charge controllers from Texas Instruments. This series is designed for straightforward charging applications where low component count and cost are primary drivers. The FP designation typically indicates an 8-pin DIP package, suitable for through-hole mounting in legacy or specific industrial designs.

Battery Chargers Replacement Considerations

Public records indicate the BQ2002 family has reached End-of-Life. Designers should evaluate equivalent NiCd/NiMH charge controllers from Texas Instruments or other manufacturers that support similar -ΔV termination and LED output functions without requiring significant circuit redesign.
