Battery Chargers Procurement Notes

Verify the exact suffix (RGET) against the manufacturer's official datasheet to confirm pinout, thermal pad configuration, and RoHS compliance status. Ensure the ordering part number matches the specific package variant required for your PCB layout. Cross-reference with the latest TI documentation to avoid discrepancies between distributor listings and official specifications.

Battery Chargers Selection Notes

Select this component when designing single-cell Li-Ion or Li-Po systems requiring high-current charging up to 4.5 A. It is suitable for applications needing I2C control for dynamic charge parameter adjustment. Consider the 24-VQFN package constraints and the 3.9 V to 17 V input voltage range during schematic design.

Battery Chargers Part Context

This part belongs to the BQ2419x series of chargers, which are designed for single-cell applications. The RGET suffix indicates a specific reel packaging format and VQFN-24 package type. It shares functional similarities with other members like the BQ24195 but may differ in specific current limits or feature sets as defined by the base model number.

Battery Chargers Replacement Considerations

Direct substitutes include other parts within the BQ2419x family such as the BQ24195RGET or BQ24196RGET, provided their electrical characteristics align with the design requirements. Verify compatibility regarding maximum charge current and package dimensions before substitution.
