XC6810A42C0R-G

Overview

The XC6810A42C0R-G is a multi-function micro battery charger IC designed for single-cell lithium-ion batteries. It features a fixed charge voltage of 4.2V and supports a programmable charging current ranging from 1mA to 25mA. The device operates with a supply voltage range of 3.5V to 28V and includes an integrated battery LED indicator. It is housed in a compact WLP-12 package measuring 1.17mm by 1.57mm, suitable for surface-mount installation.

Feature Summary

Integrates a battery status LED indicator for visual charge monitoring
Supports programmable constant-current charging control
Includes comprehensive protection against overtemperature, overvoltage, reverse current, and short circuits

Applications

Single-cell lithium-ion battery management in portable electronics
Charging solutions for devices utilizing contact power supplies
Integration with wireless charging systems requiring compact form factors

Procurement Notes

Verify the specific suffix 'C0R' corresponds to the required tape-and-reel packaging configuration and lead-free compliance status. Confirm that the 4.2V output voltage aligns with the target cell chemistry requirements. Ensure the WLP-12 footprint matches the PCB layout constraints for the intended application design.

Selection Notes

Select this component when a small footprint is critical for single-cell lithium-ion applications. The fixed 4.2V output is standard for Li-ion cells. Consider the 28V maximum input voltage limit for adapter compatibility. The inclusion of an LED driver simplifies bill-of-materials by removing external indicator components.

Part Context

This part belongs to the XC6810 series of linear charger ICs from Torex Semiconductor. The series is characterized by ultra-small packages compatible with modern wireless charging and contact-based power supply designs. It falls under the PMIC - Power Management ICs category specifically for charge management.
