XC6808A2E28R-G

Battery Chargers Overview

The XC6808A2E28R-G is a single-cell lithium-ion/polymer battery linear charger IC from the XC680x series by Torex Semiconductor. It features a 4.35V fixed charge voltage and supports a maximum charging current of 40mA, which is programmable. The device operates with a supply voltage up to 6V and includes USB interface compatibility. It incorporates fault protection mechanisms such as overcurrent, overtemperature, and reverse current protection. The component is housed in a compact 6-USP-B07 (1.8x2) surface-mount package and functions within an operating temperature range of -40°C to 85°C.

Battery Chargers Feature Summary

• Integrates battery temperature detection for enhanced safety during the charging cycle.
• Provides programmable constant-current charging capability for single-cell lithium batteries.
• Includes built-in protection against overcurrent, overtemperature, and reverse current conditions.

Battery Chargers Applications

• Charging single-cell lithium-ion or lithium-polymer batteries in portable electronic devices
• Power management systems requiring USB-compatible charging interfaces
• Compact consumer electronics utilizing small footprint surface-mount packages

Battery Chargers Procurement Notes

Verify the specific suffix 'A2' corresponds to the required 4.35V charge voltage setting before procurement, as other suffixes in the XC6808 family denote different voltage levels. Confirm the 6-USP-B07 package dimensions match your PCB layout requirements. Ensure compliance with RoHS3 standards if applicable to your manufacturing process. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity.

Battery Chargers Selection Notes

Select this component when a fixed 4.35V charge voltage is required for single-cell lithium batteries. Consider the 40mA maximum current limit suitable for low-power applications. Evaluate the 6-USP-B07 package size against available board space. Verify that the USB interface compatibility aligns with the system's power source architecture. Check thermal performance requirements within the specified operating temperature range.

Battery Chargers Part Context

This part belongs to the XC680x series of linear battery chargers designed for single-cell applications. The XC6808 variant specifically targets lithium-ion and lithium-polymer chemistries. The 'A2' suffix indicates a 4.35V charge voltage setting, distinguishing it from other variants like A3 (4.20V) or A4 (4.40V). The series emphasizes compact packaging and integrated safety features for modern portable electronics.

Battery Chargers Replacement Considerations

Direct substitutes include XC6808A3E28R-G (4.20V) and XC6808A4E28R-G (4.40V), provided the charge voltage difference is acceptable for the battery chemistry. Other XC6808 variants with different suffixes may offer alternative voltage settings but require verification of electrical compatibility.
