XC6140C20A9R-G

Overview

The XC6140C20A9R-G is a voltage monitoring integrated circuit designed for rechargeable battery applications. It features a detection voltage of 2.0V and operates within an input voltage range up to 5.5V. The device includes a built-in constant voltage (CV) charging function, allowing it to manage battery charge states directly. It utilizes a compact 4-USPQ-B05 package with dimensions of 1x1 mm, suitable for space-constrained portable electronics.

Feature Summary

• Integrated constant voltage charging capability for rechargeable batteries
• Precise voltage monitoring with fixed detection threshold
• Compact ultra-small package design for mobile devices

Applications

• Rechargeable battery management systems
• Portable electronic devices requiring power supervision
• Battery chargers with integrated monitoring functions

Procurement Notes

Verify the specific suffix 'C20A9R' against the manufacturer's official datasheet to confirm the exact detection voltage and hysteresis characteristics. Ensure the package type matches the required PCB footprint. Confirm that the CV charging parameters align with the target battery chemistry specifications before finalizing procurement orders.

Selection Notes

Select this component when a combined voltage monitor and charger controller is required for single-cell rechargeable batteries. The fixed 2.0V detection level suits applications where low-voltage cutoff is critical. Consider the package size constraints and thermal requirements associated with the small form factor during the initial design phase.

Part Context

This part belongs to Torex Semiconductor's XC6140 series, which specializes in supervisory circuits for battery-powered equipment. The series focuses on integrating monitoring and charging functions into minimal footprints, supporting the trend toward highly miniaturized consumer electronics and IoT devices requiring efficient power management solutions.

Replacement Considerations

Check for direct pin-compatible alternatives within the XC6140 family that offer different detection voltages if the 2.0V threshold does not match the system requirements. Verify functional equivalence regarding the CV charging profile and output logic levels before substituting.
