XC6124D644MR-G

Supervisors Overview

The XC6124D644MR-G is a watchdog circuit manufactured by Torex Semiconductor Ltd, designed for monitoring system integrity. It operates within a temperature range of -40°C to 85°C and utilizes an SC-74A (SOT-753) surface-mount package. The device monitors a single voltage threshold set at 4.4V. Key electrical characteristics include a quiescent current of 120 µA and a power supply rejection ratio (PSRR) of 70dB at 10kHz. The output configuration supports open-drain or open-collector functionality, ensuring reliable supervision in embedded applications.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability monitoring
• Single-channel voltage threshold detection capability
• Open-drain or open-collector output interface options

Supervisors Applications

• Embedded system supervision
• Microcontroller reset monitoring
• Industrial control unit protection

Supervisors Procurement Notes

Verify the specific suffix 'MR-G' against the official Torex datasheet to confirm pinout compatibility and thermal specifications. Ensure the SC-74A footprint matches your PCB design constraints. Cross-reference the 4.4V threshold requirement with your system's operating voltage levels to prevent false triggering during normal operation fluctuations.

Supervisors Selection Notes

Select this component when a dedicated watchdog function is required alongside voltage supervision in space-constrained designs. The SOT-753 package offers a compact solution for surface-mount assembly. Consider the 120 µA quiescent current impact on overall system power budget if battery operation is critical. Verify that the 4.4V threshold aligns with the monitored rail's nominal voltage.

Supervisors Part Context

This part belongs to the XC6124 series of supervisor circuits from Torex Semiconductor. These devices are engineered for precise voltage monitoring and timing functions in portable and industrial electronics. The series emphasizes low power consumption and high accuracy, making it suitable for applications where system stability and energy efficiency are paramount design drivers.

Supervisors Replacement Considerations

Publicly confirmed parametric equivalents include the XC6209B452MR-G. Verify functional compatibility regarding watchdog timing parameters and output drive capabilities before substitution. Ensure the replacement maintains the same SC-74A package outline for mechanical fit.
