Supervisors Procurement Notes

Verify the specific suffix MR-G against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the threshold voltage of 1.7 V aligns with your system requirements. Confirm RoHS compliance status through the latest product documentation before procurement.

Supervisors Selection Notes

Select this component when a 1.7 V detection threshold is required for single-input voltage monitoring. Consider the 200 ms reset delay and open-drain output characteristics for compatibility with downstream logic. Verify that the 1 V to 6 V input range covers your application's operational voltage spectrum.

Supervisors Part Context

This part belongs to the XC6121 series of voltage monitors from Torex Semiconductor. These devices are categorized under PMIC supervisory circuits and are commonly used in portable electronics and industrial control systems where low power consumption and reliable reset generation are critical.

Supervisors Replacement Considerations

Check for XC6121 series variants with different threshold voltages if 1.7 V is not suitable. Verify pinout compatibility with SOT-25-5 packages before substitution.
