XC6810A41G0R-G

Overview

The XC6810A41G0R-G is a multi-function micro battery charger IC designed for single-cell lithium-ion batteries. It features a fixed charge voltage of 4.1 V and supports an input supply voltage range from 3.5 V to 28 V. The device offers a programmable constant charging current between 1 mA and 25 mA. It operates within a temperature range of -40°C to +125°C and is housed in a WLP-12 package with dimensions of 1.17 x 1.57 mm.

Feature Summary

• Integrated battery status indicator for monitoring charge state
• Programmable constant charging current, timer, and voltage settings
• Comprehensive protection against overtemperature, overvoltage, reverse current, and short circuits

Applications

• Single-cell lithium-ion battery management systems
• Portable electronic devices requiring compact power solutions
• IoT sensors and wearables with limited space constraints

Procurement Notes

Verify the specific suffix G0R against the official datasheet to confirm pinout and electrical parameters match the design requirements. Ensure the application circuit supports the 28 V maximum input voltage and that thermal dissipation is adequate for the WLP-12 package under high load conditions. Confirm RoHS compliance documentation is available for regulatory adherence.

Selection Notes

Select this component when a fixed 4.1 V charge voltage is required for specific lithium-ion cell chemistries. The wide input voltage range up to 28 V allows flexibility in system power architecture. The small WLP-12 footprint makes it suitable for space-constrained designs where standard packages cannot fit. Consider the operating temperature range if the environment exceeds standard commercial limits.

Part Context

This part belongs to the XC6810 series of multi-function micro battery chargers from Torex Semiconductor. The series is characterized by its ultra-small package size and integrated safety features. The XC6810A41G0R-G specifically denotes the 4.1 V output variant within this family, differentiated by its internal voltage reference setting compared to other models like the 4.2 V versions.

Replacement Considerations

XC6810B42C0R-G and XC6810B42G0R-G are parameter-equivalent alternatives within the same series, though they feature different charge voltages (4.2 V). Verify that the system can tolerate the voltage difference before substitution.
