Battery Chargers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's datasheet to confirm RoHS compliance status and material composition changes relative to the standard BQ24113 variant. Ensure the ordering part number matches the exact package dimensions and pinout configuration required for the PCB layout. Cross-reference the latest datasheet revision to confirm any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component when designing systems that require a compact, single-inductor solution for 1S or 2S Li-Ion/Polymer batteries. The device is suitable for applications needing a maximum charge current of 2A and an input voltage capability up to 16V. Consider the 20-VQFN package size if board space is constrained. Verify that the system design accommodates the thermal requirements associated with the exposed pad package under maximum load conditions.

Battery Chargers Part Context

This part belongs to the bqSWITCHER family of battery chargers from Texas Instruments. It is functionally related to other members of the BQ241xx series, such as the BQ24103 and BQ24115, which share similar architectural features but may differ in specific electrical ratings or pin configurations. The G4 suffix typically denotes a lead-free and RoHS-compliant version of the base component.

Battery Chargers Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the BQ241xx series. Verify that any substitute component matches the 20-VQFN package outline and maintains compatibility with the existing bill of materials regarding thermal performance and control interface requirements.
