Battery Chargers Procurement Notes

Verify the specific suffix codes against the official Torex Semiconductor datasheet to ensure correct pinout and functional configuration. Confirm that the 6-USPEL package dimensions align with your PCB footprint requirements. Check RoHS compliance status directly from the manufacturer's documentation before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component when a low-profile solution is required for single-cell Li-ion or Li-polymer batteries. Ensure the input supply voltage remains within the specified 4.5 V to 6 V range. Consider the thermal dissipation capabilities of the 6-USPEL package relative to the desired 280 mA charging current in your enclosure design.

Battery Chargers Part Context

This part belongs to the XC6803 series of linear chargers from Torex Semiconductor. The series is characterized by its integration of safety features and temperature monitoring. The XC6803B4E14R-G specifically utilizes the B-series designation, which typically denotes specific internal parameter variations compared to other series members like the A-series variants.

Battery Chargers Replacement Considerations

XC6803A3E14R-G and XC6803A4E14R-G are listed as parameter-equivalent alternatives. Verify electrical compatibility and pinout alignment before substitution.
