Battery Chargers Procurement Notes

Verify the specific suffix (e.g., +T) against the manufacturer's official datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Battery Chargers Selection Notes

Select this component when designing for single-cell lithium-based battery packs requiring a compact, high-efficiency switch-mode charging solution. The TQFN-12 package suits space-constrained designs. Verify that the system input voltage falls within the 4.25 V to 12 V operating range. Confirm that the required charging current does not exceed the 2 A maximum limit and that the application benefits from the integrated fault protection features.

Battery Chargers Part Context

This IC belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It is designed as a dedicated charge management controller for portable electronics. The device integrates the necessary control logic and drivers for external switching components to manage the charging cycle safely and efficiently for standard lithium chemistry cells.

Battery Chargers Replacement Considerations

Consult official Analog Devices or Maxim Integrated substitution guides for verified compatible alternatives. Do not assume functional equivalence with generic chargers without verifying pin compatibility and electrical specifications.
