R3130N29EC3-TR-FE

Supervisors Overview

The R3130N29EC3-TR-FE is a voltage detector supervisory circuit manufactured by Nisshinbo Micro Devices. It features an internal counter type delay function and operates within a supply voltage range of 1 V to 6 V. The device monitors a single input with a threshold voltage of 2.9 V. It provides an open-drain output and includes a backup battery switch function. The reset delay time is specified at 240 ms, with an accuracy of 1.5%. It is housed in a SOT-23-3 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrates an internal counter type delay function for stable reset generation
• Supports backup battery switching for continuous monitoring during power loss
• Provides open-drain output configuration for flexible logic interfacing

Supervisors Applications

• Portable electronic devices requiring low voltage supervision
• Battery-powered systems needing backup switch functionality
• Embedded controllers requiring delayed reset signals

Supervisors Procurement Notes

Verify the specific suffix EC3 against official datasheets to confirm pinout and electrical characteristics match your design requirements. Ensure ordering quantities align with manufacturer reel specifications. Cross-reference the exact part number with authorized distributors to confirm availability and authenticity before procurement.

Supervisors Selection Notes

Select this component when a precise 2.9 V threshold with a fixed 240 ms delay is required. The open-drain output suits applications needing external pull-up resistors or wired-OR configurations. Consider the SOT-23-3 package size for space-constrained PCB layouts. Verify compatibility with the system's operating temperature range and supply voltage limits.

Supervisors Part Context

This part belongs to the R3130N series of voltage detectors from Nisshinbo Micro Devices. The series is characterized by low current consumption and high accuracy. These devices are designed for general-purpose power management in portable electronics. The R3130N29EC3 variant specifically targets applications requiring a 2.9 V detection level with integrated delay timing.

Supervisors Replacement Considerations

Check for direct substitutes within the R3130N series with different threshold voltages if voltage levels change. Verify pin-to-pin compatibility with other SOT-23-3 voltage detectors from Nisshinbo or competitors. Ensure replacement parts maintain the same delay function type and output configuration.
