Battery Chargers Procurement Notes

Verify the specific output voltage configuration required for your application, as the XC6808 series offers distinct variants for 4.20V, 4.35V, and 4.40V outputs. Ensure the selected part number suffix corresponds exactly to the target voltage level. Confirm package compatibility with the 6-USP-B07 footprint. Cross-reference the manufacturer datasheet for detailed electrical characteristics and thermal performance data before finalizing procurement.

Battery Chargers Selection Notes

Select this component when designing systems requiring a compact, single-cell linear charger with integrated thermal monitoring. The choice between 4.20V, 4.35V, and 4.40V variants depends on the specific nominal voltage and termination criteria of the target battery chemistry. Consider the 40mA maximum charge current limit for low-power applications. The 6-USP-B07 package is suitable for space-constrained surface-mount designs. Evaluate the operating temperature range of -40°C to +85°C against environmental requirements.

Battery Chargers Part Context

The XC6808A3E48R-G belongs to the XC6808 series of battery chargers from Torex Semiconductor. This series is designed for single-cell Li-ion and Li-polymer batteries. The 'A3' designation typically indicates a specific output voltage variant within the family, while 'E48' denotes the package type and tape/reel configuration. The series emphasizes safety through integrated temperature detection and multiple fault protections, targeting small form-factor portable electronics.

Battery Chargers Replacement Considerations

Direct substitutes within the same family include other XC6808 variants with different output voltages (e.g., XC6808A2E48R-G for 4.20V, XC6808A4E48R-G for 4.40V), provided the voltage matches the battery specification. Other XC680x series chargers may serve as functional alternatives if pinout and package dimensions are compatible.
