• Includes comprehensive fault protection mechanisms against over-temperature, reverse current, and short circuits

Battery Chargers Applications

• Single-cell handheld portable devices
• USB-powered consumer electronics
• Battery management in compact mobile systems

Battery Chargers Procurement Notes

Verify the RoHS compliance status carefully, as documentation indicates conflicting information regarding lead-free certification for this specific suffix variant. Confirm the active production status, as some sources list related BQ24032 models as obsolete or end-of-life. Ensure the ordering part number matches the required package and thermal specifications before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component for designs requiring integrated power-path control to optimize system performance during charging. It is suitable for applications needing a compact solution for single-cell Li-Ion or Li-Po batteries. Consider the 20-VQFN footprint for PCB layout constraints. Verify compatibility with the intended input voltage range and required charging current limits for the target application.

Battery Chargers Part Context

This device belongs to Texas Instruments' bqTINY III family of battery chargers. It shares functional similarities with other members like the BQ24032ARHLT but may differ in packaging or specific regulatory certifications. The part is designed for high-efficiency charging in space-constrained portable electronics, offering a complete solution with minimal external components.

Battery Chargers Replacement Considerations

The BQ24032ARHLT is a documented alternative within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any differences in RoHS compliance or package dimensions that might affect existing board designs.
