Battery Chargers Procurement Notes

Verify the lifecycle status before procurement as this component has been scheduled for obsolescence by Texas Instruments. Confirm availability through authorized distributors or secondary markets. Ensure the 8-PDIP package meets your PCB layout requirements. Check for RoHS compliance documentation if required for your specific manufacturing standards.

Battery Chargers Selection Notes

Select this part when designing chargers for NiCd or NiMH chemistries requiring integrated fast-charge control. The 8-PDIP package is ideal for prototyping or low-volume through-hole designs. Consider the 2A output limit and 4-6V input range against your system power constraints. Evaluate alternative active components if long-term supply assurance is critical due to discontinuation status.

Battery Chargers Part Context

This component belongs to Texas Instruments' portfolio of battery management integrated circuits. It falls under the category of charge controllers specifically optimized for rechargeable nickel-based batteries. The GPN suffix indicates the PDIP package variant. It serves as a dedicated solution for managing charge cycles without external microcontrollers.

Battery Chargers Replacement Considerations

As the BQ2002GPN is scheduled for obsolescence, identify active replacements from the same family or compatible multi-chemistry controllers. Verify pin compatibility and electrical specifications such as output current and input voltage ranges before substitution.
