XC6124E639MR-G

Supervisors Overview

The XC6124E639MR-G is a voltage monitor from Torex Semiconductor, designed for single-input supervision in surface-mount applications. It operates within a supply voltage range of 1 V to 6 V and features a detection threshold of 3.9 V. The device utilizes CMOS technology with an open-drain output type and includes a watchdog timer function. It supports battery backup switching and power failure detection without manual reset capability. The component functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact SOT-25-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer circuit for system reliability monitoring
• Supports battery backup switching functionality for continuous operation
• Detects power failure events with open-drain output signaling
• Operates on low supply voltage ranges suitable for portable electronics

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems with backup switching needs
• Embedded controllers needing watchdog protection
• Power management circuits in consumer electronics

Supervisors Procurement Notes

Verify the specific suffix MR-G against official Torex documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the SOT-25-5 housing. Cross-reference the threshold voltage code E639 with the datasheet to confirm the 3.9 V detection level matches your design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The open-drain output allows flexible interfacing with various logic levels. Consider the 1 V minimum operating voltage for low-power applications. Verify that the 3.9 V threshold aligns with the monitored rail's acceptable limits. The SOT-25-5 package offers space efficiency for dense board layouts.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors manufactured by Torex Semiconductor. The series leverages advanced CMOS technology to provide precise voltage monitoring with low current consumption. These components are categorized under PMIC supervisory circuits, offering reliable performance for protecting sensitive electronics from undervoltage or power loss conditions in modern electronic designs.

Supervisors Replacement Considerations

Check for XC6124 variants with different threshold codes if the 3.9 V detection point does not match the target voltage. Verify pinout compatibility with the SOT-25-5 package for direct replacement. Ensure the replacement maintains the open-drain output configuration and watchdog timer presence.
