XC6140N16CNR-G

Overview

The XC6140N16CNR-G is a voltage monitoring integrated circuit from Torex Semiconductor, designed for rechargeable battery applications with constant voltage charging support. It operates within a supply voltage range of 1.1 V to 6 V and features a fixed threshold voltage of 1.6 V. The device provides an open-drain output and includes manual reset functionality. It incorporates a backup switch for battery retention and exhibits a reset delay time of 224 us. The component functions reliably across an industrial temperature range from -40°C to +105°C and is housed in an SSOT-24 package.

Feature Summary

• Integrated constant voltage charging control specifically tailored for rechargeable battery management systems
• Dedicated backup switch capability to maintain data integrity during power transitions
• Manual reset input allows for explicit system initialization and state control

Applications

• Rechargeable battery voltage supervision
• Constant voltage charging circuit monitoring
• Battery backup system protection

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status through manufacturer documentation prior to integration. Cross-reference pinouts with the SSOT-24 footprint specifications to prevent assembly errors. Validate thermal performance requirements against the specified operating temperature range for the target environment.

Selection Notes

Select this component when precise monitoring of rechargeable battery voltages near 1.6 V is required alongside charging regulation. The inclusion of a backup switch distinguishes it from standard detectors, making it suitable for systems needing state preservation. Ensure the open-drain output interface aligns with the downstream logic levels. Consider the manual reset feature if deterministic startup behavior is critical for the application design.

Part Context

This part belongs to the XC6140 series of supervisory circuits by Torex Semiconductor. The series focuses on battery-powered devices requiring robust voltage monitoring and charging coordination. Unlike general-purpose detectors, these ICs integrate specific functionalities for rechargeable cell management, offering a compact solution for portable electronics and battery-operated equipment.

Replacement Considerations

Direct substitutes require matching the 1.6 V threshold, SSOT-24 package, and backup switch feature. Verify that alternative parts support the same 6 V maximum supply voltage and open-drain output configuration. Check for compatible manual reset inputs and similar reset delay characteristics to ensure functional parity.
