Supervisors Procurement Notes

Verify the specific threshold voltage designation corresponding to the '161' suffix against the official datasheet before ordering. Confirm that the DFN-PLP-1010-4 package dimensions align with your PCB footprint requirements. Ensure compatibility with the 0.5 V minimum operating voltage for your target application environment.

Supervisors Selection Notes

Select this component when a single-channel voltage detector with open-drain output is required. It is appropriate for designs prioritizing low quiescent current and compact surface-mount packaging. Consider the 40 µs reset delay for timing-sensitive logic recovery sequences.

Supervisors Part Context

This part belongs to the R3114K series of supervisory circuits from Nisshinbo Micro Devices. The series focuses on providing accurate voltage monitoring solutions with minimal power consumption. The R3114K161C-TR variant specifically targets applications requiring a defined threshold voltage within the standard operating range of the family.

Supervisors Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same DFN-PLP-1010-4 package and open-drain output configuration to preserve board compatibility.
