Battery Chargers Procurement Notes

Verify the specific suffix 'DQCR' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure that the requested quantity aligns with standard manufacturing reel sizes to avoid partial reel handling issues. Cross-reference the RoHS compliance status and moisture sensitivity level requirements with your assembly process standards before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when designing circuits exclusively for Lithium Iron Phosphate chemistry, as its fixed 3.5 V output is tailored for these cells rather than standard Lithium-Ion or Polymer types. Consider the WSON-10 package size constraints and thermal dissipation requirements associated with 1 A linear charging. Evaluate the 30 V maximum input voltage limit against your system's power source to ensure safe operation without exceeding device ratings.

Battery Chargers Part Context

This part belongs to the BQ25070 series of single-cell linear chargers from Texas Instruments.
