XC6808BNC38R-G

Overview

The XC6808BNC38R-G is a single-cell lithium-ion/polymer battery linear charger IC manufactured by Torex Semiconductor. It features an integrated USB interface for power input and supports a maximum charging current of 40mA. The device regulates the battery voltage to 4.2V, 4.35V, or 4.40V depending on the specific configuration. It includes battery temperature detection capabilities and operates within a supply voltage range up to 6V. The component is housed in a compact 6-USP-B07 (1.8x2) surface-mount package with exposed pads.

Feature Summary

• Integrates USB interface for direct connection to host devices
• Includes battery temperature detection circuitry for safety monitoring
• Provides overcurrent, overtemperature, and reverse current protection

Applications

• Single-cell lithium-ion battery charging in portable electronics
• Power management for USB-powered consumer devices
• Battery management systems requiring thermal monitoring

Procurement Notes

Verify the exact output voltage setting (4.2V, 4.35V, or 4.40V) required for your application against the datasheet specifications for this suffix. Confirm that the 6-USP-B07 package dimensions align with your PCB layout constraints. Ensure compatibility with the intended USB power source voltage levels before integration.

Selection Notes

Select this component when a low-current (40mA) linear charging solution is sufficient for small capacity cells. The integrated USB interface simplifies design for devices powered directly from USB ports. Consider the thermal performance requirements given the linear regulation topology and the need for adequate heat dissipation in the chosen package.

Part Context

This part belongs to the XC6808 series of single-cell Li-battery linear chargers from Torex Semiconductor. The series is characterized by its integration of USB connectivity and battery temperature detection functions. It is designed for applications where space efficiency and simplified external component count are priorities for managing single-cell lithium-based batteries.

Replacement Considerations

Other XC6808 variants with different voltage settings or package types may serve as functional substitutes if electrical parameters match. Verify pinout compatibility and thermal characteristics when considering alternative suffixes within the same product family.
