XC6123C548MR-G

Supervisors Overview

The XC6123C548MR-G is a single-channel voltage monitor supervisor circuit manufactured by Torex Semiconductor Ltd. It operates within a supply voltage range of 1 V to 6 V and features a fixed threshold voltage of 5.48 V. The device utilizes an SOT-25-5 surface-mount package and provides an open-drain CMOS output. Key functional parameters include a reset delay time of 50 ms, a watchdog timer, and a battery backup switch. It supports power failure detection and operates across a temperature range of -40°C to +85°C with a typical static current of 5 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a battery backup switch function for critical data protection
• Provides power failure detection capabilities
• Features low quiescent current consumption for energy efficiency

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems with backup switching needs
• Embedded controllers needing watchdog functionality
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix MR-G confirms the SOT-25-5 package and reel packaging format. Confirm the threshold voltage code corresponds to 5.48 V as indicated by the model designation. Ensure RoHS compliance documentation is available for regulatory requirements. Cross-reference the manufacturer part number with official Torex Semiconductor databases to validate authenticity and revision status before procurement.

Supervisors Selection Notes

Select this component when a fixed 5.48 V monitoring threshold is required for single-rail applications. The SOT-25-5 package suits space-constrained designs. Consider the 50 ms reset delay and watchdog integration if system stability against transient faults is critical. Verify that the 1 V minimum operating voltage aligns with the lowest expected supply rail during operation.

Supervisors Part Context

This component belongs to the XC6123 series of supervisory circuits from Torex Semiconductor. The series offers various threshold voltages and package options. The XC6123C548MR-G specifically denotes the C-series variant with a 5.48 V threshold in an SOT-25-5 tape-and-reel configuration. It is part of Torex's portfolio of CMOS power management ICs designed for low-power applications.

Supervisors Replacement Considerations

Direct substitutes must match the 5.48 V threshold, SOT-25-5 package, and integrated watchdog/backup features. Check datasheets for equivalent reset delays and output types. Generic voltage monitors without watchdog or backup functions are not suitable replacements.
