Battery Chargers Procurement Notes

Verify the specific suffix 'RGE' corresponds to the VQFN-24 package and reel packaging configuration. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer datasheet. Ensure compatibility with the intended I2C bus voltage levels and thermal dissipation capabilities for the target application environment.

Battery Chargers Selection Notes

Select this component when an I2C-controlled solution is required for single-cell battery charging. It is suitable for designs needing NVDC functionality to manage power paths between USB input and battery sources. Consider the 2 A output capability and VQFN-24 package size relative to board space constraints and thermal requirements.

Battery Chargers Part Context

This part belongs to the BQ24259 series of battery chargers. It is distinct from other variants like the BQ24253 or BQ24250 due to its specific NVDC features and I2C control capabilities. The RGER designation indicates the tape-and-reel packaging option for automated assembly processes.

Battery Chargers Replacement Considerations

Consult official substitution lists for compatible parts within the same family. Verify pinout and functional equivalence before replacing with similar models.
