XC6808B3E38R-G

Overview

The XC6808B3E38R-G is a single-cell lithium-ion battery linear charger IC manufactured by Torex Semiconductor. It features an integrated charge current control circuit that maintains constant current charging until the battery voltage reaches the fixed regulation voltage of 4.4V, after which it switches to constant voltage mode with decreasing current. The device includes a battery temperature detection function using an external NTC thermistor to monitor cell temperature during charging. It supports programmable charge currents up to 40mA and incorporates protection features such as over-current, over-temperature, and reverse current prevention.

Feature Summary

• Integrates constant current/constant voltage (CC/CV) charging profile for single-cell Li-ion batteries
• Includes battery temperature detection circuit utilizing external NTC thermistors for thermal management
• Provides comprehensive protection against over-current, over-temperature conditions, and reverse current flow

Applications

• Single-cell lithium-ion battery charging in portable electronic devices
• Consumer electronics requiring compact linear charging solutions
• Battery-powered equipment with strict thermal monitoring requirements

Procurement Notes

Verify the specific package type and marking code against official Terox Semiconductor datasheets before procurement. Confirm that the 4.4V regulation voltage aligns with your battery specifications. Ensure compatibility with your system's NTC thermistor selection for the temperature detection feature. Cross-reference the manufacturer part number XC6808B3E38R-G with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a low-component-count linear charger is required for single-cell Li-ion applications. The integrated temperature detection simplifies thermal management compared to basic chargers. Consider the maximum charge current capability relative to your battery's acceptance rate. Verify that the operating voltage range of the input supply matches your system design constraints.

Part Context

This part belongs to the XC6808 series of single-cell lithium battery chargers from Torex Semiconductor. The series is designed for applications requiring simple, cost-effective charging solutions with built-in safety features. Variants within the series typically differ in regulation voltage or package options, but share core functionalities like CC/CV charging and thermal monitoring.

Replacement Considerations

Consult Torex Semiconductor documentation for direct pin-compatible alternatives within the XC6808 family. Verify that any substitute maintains the 4.4V regulation voltage and similar protection features. Ensure the replacement supports the required 40mA charge current and compatible package dimensions.
