XC6802A42X4R-G

Overview

The XC6802A42X4R-G is a linear charge management IC designed for single-cell Lithium-ion and Lithium Polymer batteries. It provides a regulated 4.2 V output with an 800 mA constant charging current. The device operates on a supply voltage range of 4.25 V to 6 V and draws only 15 uA in standby mode. It is housed in a compact USPEL-6 package (1.8x2 mm) suitable for surface mount installation. The component supports power dissipation up to 120 mW and functions within a temperature range of -40 C to +85 C.

Feature Summary

• Linear charging architecture optimized for single-cell lithium battery systems
• Compact USPEL-6 surface-mount packaging for space-constrained designs
• Ultra-low standby current consumption for extended battery life

Applications

• Single-cell Lithium-ion battery charging
• Lithium Polymer battery management
• Portable electronic device power regulation

Procurement Notes

Verify the specific package variant, as the XC6802A series includes multiple form factors such as SOT-89-5 and USP-6C. Confirm RoHS compliance status through official documentation before integration. Ensure the selected part matches the required thermal dissipation capabilities for the target application environment.

Selection Notes

Select this component when a low-profile solution is required for single-cell lithium battery charging. The USPEL-6 package offers a smaller footprint compared to traditional SOT packages. Verify that the input voltage remains within the 4.25 V to 6 V operational range to ensure stable performance and proper regulation.

Part Context

This part belongs to the XC6802 family of linear chargers from Torex Semiconductor. The family includes variants with different packages like SOT-89-5 and USP-6C. All variants share similar electrical characteristics but differ in physical dimensions and thermal properties. The XC6802A42X4R-G specifically utilizes the USPEL-6 package for high-density applications.

Replacement Considerations

Direct substitutes include other XC6802A variants with identical electrical specifications but different packages, such as XC6802A42XPR-G or XC6802A42XER-G. Verify pinout compatibility and thermal requirements when swapping between package types.
