XC6140N19C9R-G

Overview

The XC6140N19C9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features an open-drain output and manual reset functionality without a watchdog timer. The device operates within a maximum supply voltage of 6 V and supports a threshold voltage of 2 V. It includes a battery backup switch and provides a reset delay time of 224 us. The component is housed in an SSOT-24 package, suitable for surface mount installation.

Feature Summary

• Integrated constant voltage charging function for rechargeable batteries
• Manual reset capability with open-drain output configuration
• Battery backup switch support for continuous monitoring

Applications

• Rechargeable battery voltage monitoring systems
• Constant voltage charging circuit supervision
• Portable electronic device power management

Procurement Notes

Verify the specific suffix C9 against official Torex documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with the target PCB footprint for the SSOT-24 package. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a dedicated voltage monitor with integrated CV charging control is required. The manual reset feature suits applications where system state must be explicitly managed. Verify that the 2 V threshold aligns with the battery cell chemistry requirements. Ensure the 6 V maximum supply voltage covers the peak operating conditions of the target circuit.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, which specializes in voltage monitors for rechargeable batteries. The series offers various threshold voltages and package options to accommodate different battery types and form factors.
