R3116Q311C-TR-FE

Supervisors Overview

The R3116Q311C-TR-FE is a voltage detector supervisory circuit manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 0.5 V to 6 V and features a detection threshold of 3.1 V with 0.8% accuracy. The device provides a CMOS output, includes a 100 ms reset delay function, and supports battery backup mode. It consumes 1.6 uA of operating current and functions between -40°C and +85°C in an SC-82AB-4 package.

Supervisors Feature Summary

• Provides high-accuracy voltage monitoring with 0.8% threshold precision
• Integrates a fixed 100 ms delay function to prevent false resets
• Supports battery backup operation for continuous monitoring during power loss

Supervisors Applications

• Portable electronic devices requiring low-voltage supervision
• Battery-powered systems needing backup mode functionality
• Embedded circuits utilizing CMOS-compatible logic interfaces

Supervisors Procurement Notes

Verify the specific suffix C-TR-FE against official datasheets to confirm the exact threshold voltage and package configuration. Ensure compatibility with the target system's voltage range and temperature requirements before integration. Cross-reference manufacturer documentation for any recent revisions or pinout updates.

Supervisors Selection Notes

Select this component when precise voltage monitoring is required with minimal power consumption. The 0.8% accuracy suits applications sensitive to threshold variations. The integrated delay function simplifies design by eliminating external timing components. Verify that the 6 V maximum input voltage aligns with the source supply.

Supervisors Part Context

This part belongs to the R3116Q series of low-voltage detectors designed for energy-efficient applications. The series emphasizes high accuracy and low standby current, making it suitable for portable electronics. The SC-82AB-4 package allows for compact surface-mount implementation in space-constrained designs.

Supervisors Replacement Considerations

Check for other R3116Q variants with different threshold voltages if the 3.1 V setting does not match the application needs. Ensure substitute parts maintain the same CMOS output type and delay characteristics.
