XC6802A42XMR-G

Battery Chargers Overview

The XC6802A42XMR-G is a linear charger IC designed for single-cell lithium-ion and lithium-polymer batteries. It provides a maximum charge current of 800 mA with a fixed output voltage of 4.2 V. The device operates from a supply voltage range of 4.25 V to 6 V. It features a low quiescent current of 15 uA during operation. The component is housed in an SOT-25-5 package and supports surface-mount installation. It functions within a temperature range of -40 C to +85 C.

Battery Chargers Feature Summary

• Constant-current/constant-voltage charging profile for single-cell lithium batteries
• Low quiescent current consumption for efficient power management
• Integrated thermal regulation to limit die temperature

Battery Chargers Applications

• Single-cell lithium-ion battery charging systems
• Lithium-polymer battery management circuits
• Portable electronic devices requiring compact linear charging solutions

Battery Chargers Procurement Notes

Verify the specific suffix 'XMR' confirms the SOT-25-5 package configuration required for your design. Confirm RoHS compliance status through the manufacturer's official documentation before finalizing procurement. Ensure the ordering part number matches the exact pinout and package dimensions specified in the datasheet to avoid integration errors.

Battery Chargers Selection Notes

Select this component when a compact SOT-25-5 package is preferred over larger alternatives like SOT-89 or USP. It is suitable for applications requiring up to 800 mA charge current with a 4.2 V setpoint. Consider the thermal dissipation capabilities of the SOT-25 package relative to the expected ambient temperature and load conditions.

Battery Chargers Part Context

This part belongs to the XC6802 series of linear chargers from Torex Semiconductor. The series includes variants with different packages such as SOT-89-5 (XC6802A42XPR) and USP-6C (XC6802A42XER). All variants share similar electrical characteristics but differ in physical footprint and thermal performance.

Battery Chargers Replacement Considerations

Direct substitutes include XC6802A42XPR-G (SOT-89-5 package) and XC6802A42XER-G (USP-6C package). These parts offer identical electrical specifications but require PCB layout adjustments due to different pinouts and package dimensions.
