XC6140N19A9R-G

Overview

The XC6140N19A9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a threshold voltage of 1.9 V and operates within a maximum supply voltage of 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 us. The component supports surface mount installation in an SSOT-24 package and functions across a temperature range from -40 C to +105 C.

Feature Summary

• Integrated voltage monitoring specifically tailored for rechargeable battery applications with constant voltage charging support
• Includes a dedicated battery backup switch to maintain system state during power transitions
• Provides manual reset capability allowing external control over the reset signal generation

Applications

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

Procurement Notes

Verify the specific suffix A9R-G against the official Torex Semiconductor datasheet to confirm the exact threshold voltage and package configuration. Ensure compatibility with the target operating temperature range and supply voltage limits before integration. Cross-reference the open-drain output requirements with the downstream logic interface to guarantee proper signal integrity and level shifting needs are met in the final design.

Selection Notes

Select this component when a dedicated monitor for rechargeable batteries with CV charging is required. The 1.9 V threshold suits specific cell chemistry protection levels. The open-drain output allows flexible interfacing with various logic families. Consider the SSOT-24 package size for space-constrained designs requiring surface mount technology.

Part Context

This part belongs to the XC6140 series of supervisory circuits from Torex Semiconductor. The series focuses on voltage monitoring for battery-powered devices. The N-series designation typically indicates specific output characteristics or package variations within the broader product line, distinguishing it from other variants like the C-series.

Replacement Considerations

Check for XC6140C19A9R-G as a potential alternative with CMOS output instead of open-drain. Verify if XC6140N18A9R-G or XC6140N20A9R-G meet threshold requirements. Confirm package and pinout compatibility before substitution.
