Battery Chargers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to integration. Review the official discontinuation notification dated July 16, 2025, as this part is marked obsolete. Ensure final assembly processes align with the specified surface-mount installation requirements and thermal dissipation guidelines.

Battery Chargers Selection Notes

Select this component for applications requiring a compact footprint and integrated current path management. The fixed 4.2V output suits standard single-cell lithium configurations. Consider the 10-LGA package constraints for PCB layout. Evaluate the 385mA maximum current capability against specific load requirements. Verify compatibility with USB-based input sources given the operating voltage range.

Battery Chargers Part Context

This IC belongs to the XC6806 series, designed specifically for single-cell lithium battery management. It distinguishes itself by combining linear charging with active current path control, allowing the system to run directly from the input source while charging the battery. The series targets space-constrained consumer electronics where efficiency and size are critical design parameters.

Battery Chargers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the XC6806A40511-G is officially discontinued, engineers must consult Torex Semiconductor for current portfolio alternatives or perform full electrical and mechanical re-verification if selecting generic equivalents.
