Battery Chargers Procurement Notes

Verify that the specific suffix 'CRQ1' corresponds to the required tape and reel packaging configuration and automotive qualification standards. Confirm compatibility with the target PCB footprint and soldering profile during component sourcing. Ensure the procurement source provides valid traceability documentation consistent with AEC-Q100 requirements for automotive applications.

Battery Chargers Selection Notes

Select this component when designing for single-cell Li-ion or LiFePO4 applications requiring automotive reliability and low component count. Consider its 800 mA capability against peak load demands and verify that the host USB or wall adapter can support the programmed input current limit. Evaluate the WSON package size constraints relative to available board space and thermal dissipation requirements.

Battery Chargers Part Context

This part belongs to the BQ2517x family of linear chargers from Texas Instruments. It shares functional similarities with the BQ25170 but includes specific automotive qualification markings. The Q1 designation indicates compliance with AEC-Q100 standards, distinguishing it from standard industrial grade variants within the same product line.
