XC6806B35511-G

Battery Chargers Overview

The XC6806B35511-G is a single-cell lithium-ion/polymer battery linear charger IC from Torex Semiconductor. It features a fixed output voltage of 3.55V and a maximum charge current of 385mA. The device operates within a supply voltage range suitable for standard USB or adapter inputs. It integrates shutdown functionality and current path management to optimize system performance during charging cycles.

Battery Chargers Feature Summary

• Integrates shutdown control to minimize power consumption when the system is inactive.
• Includes current path management to prioritize system load over battery charging when input voltage is low.
• Supports single-cell lithium-ion and lithium-polymer battery chemistries.

Battery Chargers Applications

• Portable electronic devices requiring single-cell battery charging
• USB-powered consumer electronics
• Battery management systems with limited input voltage headroom

Battery Chargers Procurement Notes

Verify the exact suffix and package marking against the official Torex Semiconductor datasheet to ensure compatibility with your design requirements. Confirm that the 3.55V output voltage aligns with your specific battery cell specifications. Check for any end-of-life notifications or discontinuation notices, as this part may have limited availability in the secondary market.

Battery Chargers Selection Notes

Select this component when a fixed 3.55V charging profile is required for single-cell applications. Ensure the thermal design accommodates the power dissipation associated with the 385mA charge current. Verify that the LGA-10 package dimensions fit within the available PCB real estate. Compare against other XC6806 variants if different output voltages or current limits are needed.

Battery Chargers Part Context

This part belongs to the XC6806 series of linear chargers designed for portable applications. It is distinct from switching regulators like the XC9286 series due to its linear topology. The device is intended for cost-sensitive designs where efficiency is less critical than simplicity and low noise compared to switch-mode alternatives.

Battery Chargers Replacement Considerations

Check for direct pin-to-pin replacements within the XC6806 family with adjusted voltage suffixes. Verify functional equivalence with other single-cell linear chargers if sourcing new production units is not possible due to obsolescence.
