Supervisors Procurement Notes

Verify the exact suffix MR-G against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure the detection voltage code matches the required threshold for your specific circuit design. Cross-reference the manufacturing date code and lot number if traceability is required for your production line. Confirm compliance with RoHS directives as per the official documentation.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for battery-operated applications. The fixed detection voltage of 2.7V suits systems where this specific threshold is necessary for reset or interrupt generation. Consider the SOT-23-5 footprint for PCB layout compatibility. Verify that the operating voltage range covers the minimum and maximum supply voltages of the target system.

Supervisors Part Context

This part belongs to the XC6121 series of voltage detectors from Torex Semiconductor. The series is designed for general-purpose voltage monitoring in portable equipment. The E742 designation indicates the specific detection voltage setting, while MR-G denotes the package and packaging configuration. This series emphasizes low power consumption and high precision.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the XC6121 family with different detection voltages if the threshold needs adjustment. Verify that any substitute maintains the same 0.35 µA typical current consumption and SOT-23-5 package dimensions. Ensure the replacement supports the same input voltage range and delay time characteristics.
