Battery Chargers Procurement Notes

Verify that the specific suffix matches the required charge voltage and package type, as the XC6808 series contains numerous variants with different electrical characteristics. Confirm compatibility with the target system's input voltage range and thermal requirements. Ensure the ordering information aligns with the manufacturer's official datasheet specifications to avoid functional mismatches in the final design.

Battery Chargers Selection Notes

Select this component when a low-profile, single-cell linear charger is required for lithium-based battery applications. The 4.35V output voltage makes it suitable for high-voltage lithium cells. Consider the 40mA current limit for small-capacity batteries or low-power consumer electronics where minimal heat dissipation is critical compared to switching regulators.
