XC6806C370DR-G

Battery Chargers Overview

The XC6806C370DR-G is a single-cell lithium-ion or lithium-polymer battery linear charger IC manufactured by Torex Semiconductor. It features an integrated shutdown function and a current path management feature for system power distribution. The device regulates charging voltage to 3.7V with a typical accuracy of 1%. It supports a constant-current charge rate up to 1A, determined by an external resistor. The IC includes thermal regulation to limit junction temperature during high-power dissipation. It operates within a supply voltage range of 4.25V to 5.5V. The component is housed in a compact 10-USPB (2.9x2.6mm) package.

Battery Chargers Feature Summary

• Integrated shutdown control for low-power standby modes
• Current path function for simultaneous battery charging and system powering
• Thermal regulation circuitry to prevent overheating
• Automatic termination of constant-current charging phase

Battery Chargers Applications

• Single-cell lithium-ion battery charging in portable electronics
• Lithium-polymer battery management in mobile devices
• Power management systems requiring simultaneous load and charge operation
• Compact consumer electronics with space-constrained PCB layouts

Battery Chargers Procurement Notes

Verify the exact suffix DR-G against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target input voltage range of 4.25V to 5.5V. Confirm that the required charge current does not exceed the internal thermal limits without adequate PCB copper area for heat dissipation. Cross-reference the pinout diagram with the design schematic to avoid connection errors.

Battery Chargers Selection Notes

Select this component when a linear charging solution is preferred over switching regulators for reduced electromagnetic interference. It is suitable for applications where the input voltage source is stable and close to the battery voltage. Consider the thermal performance requirements if the input-to-output voltage differential is large. Verify that the 1A maximum charge current meets the battery specification. The integrated current path feature simplifies designs requiring uninterrupted system power during charging.

Battery Chargers Part Context

This part belongs to the XC6806 series of single-cell battery chargers from Torex Semiconductor. The series is designed for cost-effective and space-efficient charging solutions. The XC6806C370 variant specifically targets 3.7V nominal lithium batteries. The DR-G suffix indicates the surface-mount packaging configuration. This family integrates protection features typically found in discrete charging circuits.

Battery Chargers Replacement Considerations

Direct substitutes include other XC6806 series variants with different output voltages or current ratings, such as XC6806A440DR-G for 4.2V outputs. Verify pin compatibility and thermal characteristics before substitution. Alternative linear chargers from other manufacturers may require external components for similar functionality.
