XC6121A739MR-G

Supervisors Overview

The XC6121A739MR-G is a single-channel voltage supervisor IC manufactured by Torex Semiconductor Ltd. It monitors system voltages and generates a reset signal when the input voltage falls below or exceeds specific thresholds. The device features an open-drain or open-collector output configuration, allowing for flexible interface with various logic families. It operates within a temperature range of -40°C to 85°C and is housed in a compact SOT-25-5 surface-mount package. The typical reset timeout is 800ms, ensuring stable system recovery after power events.

Supervisors Feature Summary

• Provides reliable voltage monitoring for single-channel applications
• Features open-drain/open-collector output for versatile logic compatibility
• Ensures system stability with defined reset timeout characteristics

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the exact suffix MR-G against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure the sourcing channel provides original components with traceable documentation. Cross-reference the part number with official distributor catalogs to avoid counterfeit risks. Confirm that the supplier can provide valid test reports or authenticity certificates upon request.

Supervisors Selection Notes

Select this component when a single-channel supervisor with open-drain output is required. Consider the 800ms typical reset timeout for application timing requirements. Verify that the operating temperature range of -40°C to 85°C meets environmental conditions. Compare threshold voltages with other XC6121 variants if different trip points are needed.

Supervisors Part Context

This part belongs to the XC6121 series of voltage supervisors from Torex Semiconductor. The series offers various threshold options and output configurations. The XC6121A739MR-G specifically denotes a particular threshold voltage and package type within this family. It is designed for cost-effective and space-constrained electronic designs requiring basic power management supervision.

Supervisors Replacement Considerations

Check for direct substitutes within the XC6121 series with compatible threshold voltages. Verify pin-to-pin compatibility with alternative supervisor ICs from other manufacturers. Ensure equivalent reset timeout and operating temperature ranges before substitution.
