XC6122C626MR-G

Supervisors Overview

The XC6122C626MR-G is a high-precision voltage monitor with an integrated watchdog timer manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.0 V to 6.0 V and features a fixed detection threshold of 2.6 V. The device utilizes a CMOS process, drawing a typical operating current of 12 µA and a static current of 5 µA. It provides a CMOS open-drain output and includes a built-in delay circuit for release timing. Packaged in a compact SOT-25-5 surface-mount format, it supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detector with a dedicated watchdog timer function
• Features low power consumption suitable for battery-operated applications
• Includes a built-in delay circuit eliminating the need for external components
• Provides an open-drain output structure for flexible logic interfacing

Supervisors Applications

• Microprocessor system reset circuits
• Watchdog timer monitoring for embedded controllers
• Memory backup power switching control
• Power failure detection in portable devices

Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's official datasheet to confirm the package type and tape/reel specifications. Ensure the required detection voltage of 2.6 V aligns with the target application's threshold requirements. Confirm compliance with RoHS directives and check for any lead-free manufacturing certifications prior to final procurement authorization.

Supervisors Selection Notes

Select this component when a single-channel voltage supervision with independent watchdog functionality is required. The SOT-25-5 package offers space efficiency for dense PCB layouts. Consider the 2.6 V threshold relative to the monitored rail stability. The low quiescent current makes it appropriate for energy-constrained designs where standby power loss must be minimized during normal operation.

Supervisors Part Context

This part belongs to the XC6121/XC6122 series of voltage detectors with watchdog functions. The series employs CMOS technology to achieve high accuracy and low current draw. The XC6122 variant specifically integrates the watchdog timer alongside the voltage monitor, distinguishing it from basic reset generators. It is designed for reliable operation in industrial and consumer electronic environments.

Supervisors Replacement Considerations

Cross-reference with other XC6122 variants sharing the SOT-25-5 package if pin compatibility is critical. Verify that alternative parts support the same 2.6 V detection threshold or accept adjustable thresholds. Ensure substitute components maintain the 1.0 V to 6.0 V operating voltage range and identical output drive characteristics.
