XC6140N18A9R-G

Overview

The XC6140N18A9R-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 within an SSOT-24 package. The device operates with a maximum supply voltage of 6 V and includes a backup battery switch. Key electrical parameters include a threshold voltage of 1.8 V, a reset delay time of 224 us, and a single monitored input. The component supports surface mount installation and functions across a temperature range from -40 C to +105 C.

Feature Summary

• Integrated constant voltage charging control for rechargeable battery applications
• Manual reset capability allows user-initiated system recovery
• Backup battery switch maintains monitoring function during main power loss

Applications

• Rechargeable battery voltage supervision
• Constant voltage charging circuit protection
• System reset management in portable electronics

Procurement Notes

Verify the specific suffix 'N' indicates the open-drain output type when sourcing replacements. Confirm the '18' code corresponds to the 1.8 V threshold requirement for your target battery chemistry. Ensure the SSOT-24 package footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this variant over CMOS output versions if your design requires an open-drain interface for wired-OR configurations or level shifting. The manual reset feature distinguishes it from auto-reset models, providing explicit control over system initialization states during fault conditions.

Part Context

This component belongs to the XC6140 series of supervisory circuits manufactured by Torex Semiconductor. The series specializes in voltage monitoring for battery-powered devices, offering various threshold voltages and output types to accommodate different system architectures and safety requirements.

Replacement Considerations

XC6140N16A9R-G (1.6V threshold), XC6140N20A9R-G (2.0V threshold). Verify threshold voltage compatibility before substitution.
