XC6123D442MR-G

Supervisors Overview

The XC6123D442MR-G is a single-channel supervisor IC manufactured by Torex Semiconductor Ltd. It operates within an ambient temperature range of -40°C to +85°C and utilizes a surface-mount SOT-25 (SC-74A) package with five pins. The device functions as a watchdog circuit with a fixed voltage threshold of 4.2V. It is RoHS compliant and lead-free, designed for reliable power management supervision in electronic systems requiring precise voltage monitoring and reset control.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system stability
• Fixed voltage threshold detection at 4.2V
• Compact SOT-25 surface-mount packaging for high-density mounting

Supervisors Applications

• Microprocessor reset circuitry
• Power-on reset circuits
• System battery backup circuits

Supervisors Procurement Notes

Verify the specific suffix 'MR-G' corresponds to the SOT-25 package and RoHS compliance status. Confirm the 4.2V threshold matches the design requirement. Ensure the supplier provides official datasheets from Torex Semiconductor Ltd. Check for any specific handling requirements due to the CMOS construction. Validate that the component meets the required operating temperature range of -40°C to +85°C for the intended application environment.

Supervisors Selection Notes

Select this component when a dedicated watchdog supervisor with a fixed 4.2V threshold is required. It is suitable for applications needing integrated reset generation without external timing components. Consider the SOT-25 package size for space-constrained designs. Ensure the input voltage exceeds the threshold during normal operation. Verify compatibility with the microprocessor's reset signal requirements.

Supervisors Part Context

This part belongs to the XC6123 series of supervisors from Torex Semiconductor. These devices are designed for power supply monitoring and reset generation. The series typically includes features like delay timers and threshold detectors. The XC6123D442MR-G specifically integrates watchdog functionality, distinguishing it from simple voltage detectors or standard reset controllers in the same family.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the XC6123 series with compatible thresholds. Verify if other Torex supervisors offer similar watchdog features in SOT-25 packages. Ensure substitute parts maintain the 4.2V threshold and operating temperature range. Cross-reference package dimensions and electrical characteristics before substitution.
