XC6140N16ANR-G

Overview

The XC6140N16ANR-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a threshold voltage of 1.6 V and operates within a power supply range up to 6 V. The device provides an open-drain output type and includes manual reset functionality without a watchdog timer. It incorporates a battery backup switch and has a reset delay time of 224 µs. Operating temperatures range from -40°C to +105°C, housed in an SSOT-24 package.

Feature Summary

• Integrated constant voltage charging control for rechargeable batteries
• Manual reset capability with defined reset delay timing
• Battery backup switch support for data retention during power loss

Applications

• Rechargeable battery monitoring systems
• Constant voltage charging circuit supervision
• Portable electronic devices requiring battery protection

Procurement Notes

Verify the specific suffix 'N16' corresponds to the required 1.6 V threshold voltage when sourcing. Confirm the SSOT-24 package availability matches your PCB footprint requirements. Ensure the open-drain output configuration aligns with your system's logic interface needs. Cross-reference the manufacturer datasheet for any recent revisions or pinout updates before finalizing procurement orders.

Selection Notes

Select this component when a dedicated voltage monitor with integrated CV charging control is required for single-cell rechargeable batteries. The open-drain output necessitates an external pull-up resistor compatible with the target logic voltage. Consider the 224 µs reset delay for timing-sensitive applications. Verify that the 6 V maximum operating voltage exceeds the maximum expected battery charge voltage plus any transient spikes.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, specialized for rechargeable battery management. Unlike general-purpose supervisors, it combines voltage monitoring with charging control functions. The series offers various threshold voltages, with the N16 variant specifically set at 1.6 V. It targets applications needing compact solutions for battery-powered electronics with strict space constraints.

Replacement Considerations

Direct substitutes must match the 1.6 V threshold, SSOT-24 package, and open-drain output. Check for equivalent manual reset and backup switch features. Generic voltage monitors lacking CV charging integration are not suitable replacements unless the charging function is handled externally.
