XC6806B440DR-G

Battery Chargers Overview

The XC6806B440DR-G is a single-cell lithium-ion/polymer battery linear charger IC manufactured by Torex Semiconductor. It features a shutdown function and a current path management capability, allowing the system load to be powered directly from the input source during charging operations. The device integrates programmable constant-current and constant-voltage charging profiles with termination logic. It includes comprehensive protection mechanisms such as over-temperature, over-current, and reverse current safeguards. The component operates within an ambient temperature range of -40°C to +85°C and is housed in a compact 10-USPB surface-mount package.

Battery Chargers Procurement Notes

Verify the exact output voltage setting against the datasheet specifications, as suffixes often denote specific fixed voltage options. Confirm the package type matches the PCB footprint requirements. Ensure the ordering part number aligns with the manufacturer's current production status, as availability may vary. Cross-reference the revision level to guarantee compatibility with existing design implementations.

Battery Chargers Selection Notes

Select this component when a single-cell lithium battery requires linear charging with integrated system power management. The current path feature distinguishes it from standard chargers by enabling load operation during recharge. Verify that the input voltage range accommodates the available power source. Consider the thermal performance requirements given the linear topology and expected load currents in the target application environment.

Battery Chargers Part Context

This part belongs to the XC6806 series of battery chargers from Torex Semiconductor. The series focuses on single-cell applications with integrated protection and control features. The XC6806B variant specifically denotes the inclusion of the current path function alongside standard charging capabilities. This family targets cost-sensitive and space-constrained portable designs requiring reliable power management.

Battery Chargers Replacement Considerations

Direct substitutes must match the 4.4V nominal output voltage and current path functionality. Verify package compatibility with the 10-USPB form factor. Check for equivalent shutdown pin configurations and protection circuit behaviors. Consult manufacturer cross-reference lists for validated alternatives with identical electrical characteristics.
