Battery Chargers Procurement Notes

Verify the specific suffix 'B39511' confirms the 4.35V output voltage variant. Confirm the 'G' suffix indicates RoHS compliance status as per the manufacturer's latest documentation. Check for obsolescence notices, as similar XC6806 variants have been marked as discontinued by distributors. Ensure the 10-LGA-B01 package footprint matches the design layout requirements.

Battery Chargers Selection Notes

Select this part when a fixed 4.35V charge voltage is required for specific lithium cell chemistries. The integrated current path function simplifies designs needing seamless power switching between input source and battery. Verify that the 385mA maximum current capability meets the target application's charging speed requirements. Ensure the 5.5V maximum input voltage aligns with the available power supply rails.

Battery Chargers Part Context

This component belongs to the XC6806 series of linear charger ICs designed for single-cell applications. The series emphasizes integration of shutdown and current path functions to reduce external component count. The B39511 designation specifies the electrical parameters, particularly the charge voltage setting. The device represents Torex's approach to compact, protected charging solutions for mobile devices.

Battery Chargers Replacement Considerations

Direct substitutes may be limited due to the specific 4.35V voltage setting and package type. Review other XC6806 variants with different voltage suffixes if the 4.35V requirement can be adjusted. Consider general single-cell linear chargers with similar 10-LGA packages if pin compatibility allows. Verify functional equivalence regarding shutdown and current path features before substitution.
