XC6140N20C9R-G

Overview

The XC6140N20C9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a single monitored input and an open-drain output type. The device operates within a maximum power supply voltage of 6 V and includes manual reset functionality without a watchdog timer. Key electrical parameters include a threshold voltage of 2 V, a reset delay time of 224 µs, and a battery backup switch feature. The component supports surface mount installation in an SSOT-24 package.

Feature Summary

• Integrated constant voltage charging function specifically tailored for rechargeable battery applications
• Manual reset capability allowing user-controlled system recovery states
• Battery backup switch support to maintain monitoring during power transitions

Applications

• Voltage monitoring for rechargeable battery systems
• Constant voltage charging circuit supervision
• Portable electronic device power management

Procurement Notes

Verify the specific suffix codes against official Torex documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Check regional availability as distribution may vary by location. Ensure the selected variant matches the required operating temperature range and output type specifications for the target design.

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 requires appropriate pull-up resistor selection based on the load logic levels. Verify that the 2 V threshold aligns with the specific battery chemistry cutoff requirements. Consider the SSOT-24 package constraints for PCB layout and thermal management in compact designs.
