XC6140N20ANR-G

Overview

The XC6140N20ANR-G is a voltage monitoring integrated circuit designed for rechargeable battery applications, featuring constant voltage (CV) charging control. Manufactured by Torex Semiconductor, it operates within a supply voltage range up to 6 V and includes a manual reset function with an open-drain output. The device detects input voltages at a threshold of 2 V and provides a reset delay of 224 µs. It supports battery backup switching and functions reliably across an extended temperature range from -40°C to +105°C. Packaged in an SSOT-24 format, this supervisory circuit integrates essential monitoring capabilities for portable electronic systems requiring precise power management.

Feature Summary

• Integrates constant voltage charging control specifically optimized for rechargeable battery management
• Includes manual reset functionality with open-drain output capability
• Supports battery backup switching to maintain system integrity during power transitions

Applications

• Rechargeable battery powered devices
• Portable electronics requiring voltage supervision
• Systems utilizing constant voltage charging protocols

Procurement Notes

Verify the specific suffix ANR against the official Torex datasheet to confirm package type and tape/reel specifications. Ensure the 2 V threshold aligns with the target battery chemistry requirements. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the SSOT-24 footprint with PCB layout guidelines to ensure mechanical compatibility. Validate operating temperature ranges against environmental conditions.

Selection Notes

Select this component when constant voltage charging integration is required alongside voltage monitoring. The 2 V threshold suits specific low-voltage battery architectures. Consider the manual reset feature if external control over the reset state is necessary. The wide operating temperature range supports industrial or automotive environments. Verify that the open-drain output interface matches the downstream logic requirements.

Part Context

This part belongs to the XC6140 series of voltage monitoring ICs from Torex Semiconductor. The series focuses on rechargeable battery applications, distinguishing itself by integrating CV charging control features not found in standard supervisors. The N20 designation indicates the specific detection voltage level. The ANR suffix typically denotes the SSOT-24 package configuration.

Replacement Considerations

Direct substitutes include other XC6140 variants with different voltage thresholds or package options. Compare XC6140NxxANR-G models where xx represents alternative detection voltages. Ensure functional equivalence regarding the manual reset and CV charging integration before substitution.
