Battery Chargers Procurement Notes

Verify the specific output voltage configuration (4.20V, 4.35V, or 4.40V) required by your design, as the XC6808 series offers distinct part numbers for each voltage setting. Confirm that the application environment stays within the specified -40°C to +85°C operating temperature range. Ensure the PCB layout accommodates the USP-6B07 package dimensions and thermal requirements for the 750 mW power dissipation rating. Cross-reference the datasheet for exact pinout and electrical characteristics before finalizing the bill of materials.

Battery Chargers Selection Notes

Select this component when designing for single-cell Li-ion or Li-polymer batteries requiring a linear charging solution with integrated thermal monitoring. The choice depends on matching the required output voltage (4.20V, 4.35V, or 4.40V) to the specific battery chemistry. Consider the 40 mA maximum charge current limit and the 100 µA operating current for low-power applications. The USP-6B07 package size should fit the available board space constraints.

Battery Chargers Part Context

The XC6808A4E38R-G belongs to the XC6808 series of single-cell linear charger ICs manufactured by Torex Semiconductor.
