Procurement Notes

Verify the specific suffix GQW against the manufacturer's official datasheet to confirm pinout and thermal pad configuration. Confirm RoHS compliance status as documentation may vary by production batch. Ensure proper ESD handling procedures are followed during assembly due to the exposed pad design and moisture sensitivity classification.

Selection Notes

Select this component when a low-cost, fully integrated solution for single-cell Li-Ion charging is required. It is suitable for designs where space is limited due to the small 10-WFDFN package. Verify that the application requires a maximum input current of 1.2A and standard 4.2V termination voltage for optimal performance.
