XC6124C649MR-G

Supervisors Overview

The XC6124C649MR-G is a supervisory circuit manufactured by Torex Semiconductor Ltd, designed for precise voltage monitoring applications. It operates within a supply voltage range of 1 V to 6 V and features a detection threshold of 4.9 V. The device utilizes an SOT-25-5 package with CMOS open-drain output. Key electrical parameters include a reset delay time of 50 ms, a maximum operating temperature of +85 °C, and a minimum of -40 °C. It draws a typical operating current of 12 µA and includes power failure detection capabilities.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability
• Features battery backup switch for continuous monitoring during power loss
• Provides power failure detection to alert system controllers

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Industrial equipment with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's latest datasheet to confirm pinout compatibility and tolerance specifications. Ensure the required threshold voltage matches the application design before ordering. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the package type SOT-25-5 with your PCB footprint library to avoid assembly errors.

Supervisors Selection Notes

Select this component when a fixed 4.9 V threshold is required for single-input voltage monitoring. Consider the 50 ms reset delay and watchdog feature if system stability depends on automated recovery from fault conditions. Evaluate the 12 µA operating current against total system power budgets. Compare against other XC6124 variants if different threshold voltages or package options are needed for space constraints.

Supervisors Part Context

This part belongs to the XC6124 series of multi-function voltage detectors from Torex Semiconductor. These devices are built using advanced CMOS technology to achieve high accuracy and low power consumption. The series typically offers various threshold voltages and package options to suit diverse embedded system requirements while maintaining consistent performance characteristics across the family.

Supervisors Replacement Considerations

Check XC6124CxxxxMR-G variants for alternative threshold voltages within the same package. Verify XC6138 series for similar functions with separate sense pins if layout flexibility is required.
