Battery Chargers Procurement Notes

Verify the specific suffix RGER against official datasheets to confirm the tape and reel packaging configuration. Ensure compatibility with the target PCB footprint, specifically the 24-VQFN package dimensions. Confirm that the application environment remains within the specified -40°C to +85°C operational temperature limits. Validate input voltage sources do not exceed the 10 V maximum rating during normal operation.

Battery Chargers Selection Notes

Select this component when designing systems requiring high-efficiency charging from standard USB or wall adapter inputs. It is suitable for applications needing integrated power path management to maintain system uptime. Consider the 24-VQFN package size constraints and thermal dissipation requirements. Verify that the single-cell lithium-ion chemistry aligns with the 4.2 V output specification.

Battery Chargers Part Context

This part belongs to the BQ2416x family of battery chargers from Texas Instruments. The series includes variants like the BQ24165 and BQ24167, which share similar core functionalities but may differ in pin configurations or specific feature sets.
