R3116N271C-TR-FE

Supervisors Overview

The R3116N271C-TR-FE is a voltage detector from the Nisshinbo Micro Devices R3116N series, designed for monitoring single-input power supplies. It features a fixed threshold voltage of 2.7 V with an accuracy of ±0.8%. The device operates within a supply voltage range of 0.5 V to 6 V and draws a typical operating current of 1.4 µA. It provides an open-drain output and includes a reset delay function of 100 ms. The component supports battery backup switching and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with high threshold accuracy for reliable system monitoring
• Supports low-voltage operation starting at 0.5 V with minimal quiescent current consumption
• Integrates a dedicated reset delay timer to prevent false triggering during power transitions
• Includes battery backup switch functionality to maintain detection during main power loss

Supervisors Applications

• Monitoring microcontroller power rails in embedded systems
• Supervising battery-powered devices requiring low standby current
• Ensuring stable reset signals in portable electronic equipment
• Protecting memory circuits during power-down sequences

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and tolerance specifications. Ensure compatibility with your PCB footprint, as this part utilizes SOT-23-5 or SC-82AB-4 packages depending on the variant. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and environmental certifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required with tight accuracy constraints. Consider the 100 ms delay feature if noise immunity during power-up is critical. Evaluate the 1.4 µA current draw against total system budget requirements. Confirm that the open-drain output interface matches the input requirements of the downstream logic or microcontroller reset pin.

Supervisors Part Context

This part belongs to the R3116N series of voltage detectors, which are optimized for low-power applications. The series offers various threshold voltages and packaging options to suit different design needs. The R3116N271C-TR-FE specifically targets applications needing a 2.7 V reference point with high precision and low power consumption in a compact surface-mount package.

Supervisors Replacement Considerations

Check for other R3116N variants with similar thresholds but different packages or accuracies. Verify if alternative manufacturers offer comparable voltage detectors with identical pinouts and electrical characteristics. Ensure any substitute maintains the same delay time and backup switch functionality.
