XC6810B44J0R-G

Overview

The XC6810B44J0R-G is a multi-function micro battery charger IC manufactured by Torex Semiconductor, designed for single-cell Lithium-ion batteries. It operates with a fixed charge voltage of 4.4 V and supports a programmable charging current range from 1 mA to 25 mA. The device is housed in a compact WLP-12 package (1.17x1.57 mm) suitable for surface mount installation. It features an integrated battery status indicator and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated battery status indicator for visual charge level monitoring
• Programmable constant-current charging capability for precise power management
• Compact wafer-level packaging optimized for space-constrained mobile designs

Applications

• Single-cell Lithium-ion battery charging in portable electronics
• Power management in compact wearable devices
• Battery management systems requiring minimal board space

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific datasheet revisions prior to integration. Ensure supply chain stability as availability may be restricted in certain regions. Validate that the WLP-12 package dimensions align with PCB footprint requirements.

Selection Notes

Select this model when a 4.4 V fixed output voltage is required for specific Lithium-ion cell chemistries. The 1 mA to 25 mA current range suits low-power applications where high-speed charging is unnecessary. The wide operating temperature range up to +125°C allows deployment in harsh environments. Compare against other XC6810 variants if different voltage outputs or LED indicators are needed.

Part Context

This component belongs to the XC6810 series of multi-function micro battery chargers from Torex Semiconductor. The series offers various fixed voltage options and package configurations tailored for portable devices. The XC6810B44J0R-G specifically denotes the 4.4 V output variant with a battery status indicator feature.

Replacement Considerations

XC6810B44C0R-G serves as a parameter-equivalent alternative within the same series, differing primarily in the indicator type.
