R3112Q171A-TR-FE

Supervisors Overview

The R3112Q171A-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It features a threshold voltage of 1.7 V with an overvoltage threshold of 1.734 V and an accuracy of 2%. The device operates within a supply voltage range of 0.7 V to 6 V, consuming 1 uA of operating current. It provides a reset delay time of 100 ms and utilizes an SC-82AB-4 package. The output type is CMOS, and it supports battery backup switching without manual reset or watchdog timer functions.

Supervisors Feature Summary

• Provides precise voltage monitoring with high accuracy for system supervision
• Incorporates an output delay function to ensure stable signal transitions
• Supports battery backup switching for continuous operation during power loss

Supervisors Applications

• Portable electronic devices requiring low power supervision
• Battery-powered systems needing reliable voltage monitoring
• Embedded circuits utilizing single-input voltage detection

Supervisors Procurement Notes

Verify the specific suffix TR-FE indicates reel packaging when sourcing components. Confirm the SC-82AB-4 package dimensions match your PCB footprint requirements. Ensure the 1.7 V threshold aligns with your system's critical voltage levels. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit inventory. Check RoHS compliance documentation for environmental regulatory adherence.

Supervisors Selection Notes

Choose this component when a fixed 1.7 V threshold is required for supervisory applications. The CMOS output interface suits digital logic integration without additional buffering. Low quiescent current makes it suitable for energy-constrained designs. Verify that the 100 ms delay meets your system's startup timing constraints. Consider the SC-82AB-4 package size for space-limited board layouts.

Supervisors Part Context

This part belongs to the R3112Q series of low voltage detectors from Nisshinbo. The series offers various threshold voltages tailored for different supply rails. The Q-series typically features CMOS outputs and compact packaging options. These devices are designed for general-purpose voltage monitoring in consumer electronics and industrial applications.

Supervisors Replacement Considerations

Direct substitutes include other R3112Q variants with identical 1.7 V thresholds but different packages. Cross-reference R3112N series parts if SOT-23-5 packaging is acceptable. Verify electrical parameters match before substitution.
