XC6806C44511-G

Battery Chargers Overview

The XC6806C44511-G is a single-cell lithium-ion/polymer battery linear charger IC from Torex Semiconductor. It features a fixed 4.35V output voltage and supports up to 385mA programmable charging current. The device operates on a supply voltage range of 4.5V to 5.5V with a typical quiescent current of 200µA. It utilizes a compact 10-LGA (2.5x1.6mm) surface-mount package. The component includes integrated shutdown functionality, current path management, and comprehensive protection against overcurrent, overtemperature, and reverse current conditions.

Battery Chargers Feature Summary

• Integrates current path function for seamless system power management during charging
• Includes dedicated shutdown pin for low-power mode control
• Provides built-in thermal regulation and overcurrent protection mechanisms

Battery Chargers Applications

• Single-cell lithium-ion battery charging in portable electronics
• Power management for USB-powered devices
• Battery backup systems requiring current path switching

Battery Chargers Procurement Notes

Verify the exact suffix 'C44511' to confirm the 4.35V output specification and 10-LGA package type. Cross-reference the manufacturer datasheet for pinout compatibility and electrical limits. Confirm RoHS compliance status and check for any recent production discontinuation notices or alternative part recommendations from the supplier.

Battery Chargers Selection Notes

Select this component when a fixed 4.35V charge voltage is required for specific lithium chemistry cells. The integrated current path feature makes it suitable for applications where the system must remain powered while the battery charges. Ensure the input supply voltage stays within the 4.5V to 5.5V operational range for proper regulation.

Battery Chargers Part Context

This part belongs to the XC6806 series of linear chargers designed for single-cell batteries. It distinguishes itself through the inclusion of a current path controller and shutdown capability, which are not present in all basic charger variants. The 10-LGA package offers a small footprint compared to larger SOT packages used in older generations.

Battery Chargers Replacement Considerations

Consult official substitution lists for equivalent voltage and package options. Verify that replacement parts support the same current path and shutdown functionalities if these features are critical to the design.
