XC6121F743MR-G

Supervisors Overview

The XC6121F743MR-G is a single-channel voltage supervisor IC manufactured by Torex Semiconductor Ltd. It operates within an ambient temperature range of -40°C to +85°C and is housed in a surface-mount SC-74A (SOT-753) package, also referred to as SOT-25-5. The device features an open-drain or open-collector output configuration, designed to monitor supply voltages and generate reset signals for digital systems.

Supervisors Feature Summary

• Single-channel supervision capability
• Open-drain or open-collector output interface
• Wide operating temperature range

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered system monitoring
• Embedded controller supervision

Supervisors Procurement Notes

Verify the specific suffix 'F' against the official datasheet to confirm the exact threshold voltage and release time characteristics. Ensure the SC-74A/SOT-753 footprint matches the target PCB design. Confirm lead times with authorized distributors as availability may vary.

Supervisors Selection Notes

Select this component when a single-channel supervisor with open-drain/open-collector output is required. Verify that the fixed threshold voltage corresponds to the monitored rail. Consider the -40°C to +85°C operating range for industrial or commercial applications requiring robust environmental performance.

Supervisors Part Context

This part belongs to the XC6121 series of voltage supervisors from Torex Semiconductor. These ICs are designed for precise voltage monitoring in portable and industrial electronics. The series offers various threshold options and output configurations to suit different system requirements.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the XC6121 series with matching threshold voltages. Verify that substitute parts support the same SC-74A package and output type.
