Overview
The BQ2005S is a switch-mode battery charger IC designed for sequential charging of dual NiCd and NiMH battery packs. Manufactured by Benchmarq Microelectronics Inc, this component supports multi-chemistry applications. It is housed in a 20-SOIC package with a width of 7.50mm (0.295 inches). The device functions as a fast-charge controller specifically optimized for managing the charging cycles of two separate battery packs in sequence.
Feature Summary
- Supports sequential charging architecture for dual battery packs
- Compatible with Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) chemistries
- Utilizes switch-mode regulation for efficient power management
Applications
- Sequential charging systems for dual NiCd battery packs
- Sequential charging systems for dual NiMH battery packs
- Multi-chemistry battery management units requiring switch-mode control
Procurement Notes
Verify manufacturer attribution carefully, as sources list both Benchmarq and Texas Instruments for this part number. Confirm the specific datasheet version matches your design requirements. Ensure the 20-SOIC package dimensions align with your PCB layout constraints before procurement.
Selection Notes
Select this component when sequential charging of two distinct battery packs is required rather than parallel charging. It is suitable for designs utilizing NiCd or NiMH cells where switch-mode efficiency is preferred over linear regulation. Verify compatibility with the specific voltage and current requirements of the target battery chemistry.
Part Context
This IC belongs to the family of battery chargers focused on nickel-based chemistries. While often associated with Benchmarq, documentation also links it to Texas Instruments, indicating potential lineage or rebranding within the PMIC sector. It serves specialized applications requiring precise control over dual-pack charging sequences.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Due to the specific sequential charging architecture and potential manufacturer discrepancies between Benchmarq and TI, direct pin-to-pin replacements cannot be verified without additional official cross-reference data.
