• Includes built-in linear charge regulator with adjustable current limiting and thermal regulation
• Features bi-color LED status indicators for charging and fault conditions

Battery Chargers Applications

• Personal Digital Assistants (PDAs)
• Internet appliances
• Portable consumer electronics

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' confirms lead-free and RoHS compliance as per Texas Instruments standards. Confirm the package marking matches the 20-HTSSOP physical dimensions. Ensure the operating environment stays within the specified -20°C to +70°C range for optimal performance. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Battery Chargers Selection Notes

Select this component for applications requiring a fully integrated solution for single-cell lithium-ion batteries. It is suitable where board space is limited due to the high level of integration. Consider the 1 A maximum charge current capability against battery specifications. Evaluate the need for bi-color LED indication versus simpler status methods.

Battery Chargers Part Context

This part belongs to the BQ2400x family of charge management ICs from Texas Instruments. These components are engineered specifically for small form-factor portable devices. The family shares common architecture but varies in cell count and feature sets. The BQ24001 represents the single-cell variant optimized for PDAs and similar internet-enabled handhelds.

Battery Chargers Replacement Considerations

Direct replacements include other variants within the BQ2400x series such as the BQ24001PWP or BQ24001RGW. Verify pinout compatibility before substitution. Alternative single-cell chargers may require external FETs and additional discrete components.
