R3134N28EC-TR-FE

Supervisors Overview

The R3134N28EC-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices, designed for monitoring single-input supply voltages. It operates within a maximum power supply voltage of 6 V and features a threshold voltage of 2.8 V. The device utilizes an SOT-23-5 surface-mount package and provides a CMOS output type. Key operational parameters include a reset delay time of 240 ms and manual reset capability. It supports a battery backup switch function and lacks a watchdog timer. The component functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a built-in delay circuit to prevent false triggering during power transitions.
• Supports manual reset functionality for controlled system recovery.
• Includes a battery backup switch feature to maintain detection during power loss events.

Supervisors Applications

• Monitoring power supply voltages in portable electronic devices
• Providing supervision for microcontroller systems requiring stable power levels
• Ensuring reliable operation in industrial control circuits with variable input conditions

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the required threshold voltage and output configuration. Confirm RoHS compliance status and environmental certifications prior to procurement. Validate that the SOT-23-5 package dimensions align with the target PCB layout constraints.

Supervisors Selection Notes

Select this component when a fixed 2.8 V threshold is required for single-channel voltage supervision. Consider the CMOS output drive capability and 240 ms delay duration for timing-sensitive applications. Evaluate the manual reset requirement against automatic reset alternatives if system design permits. Verify that the operating voltage range and temperature specifications meet the environmental demands of the final assembly.

Supervisors Part Context

This part belongs to the R3134N series of low voltage detectors from Nisshinbo Micro Devices. The series offers various threshold voltages and packaging options to suit different monitoring needs. The R3134N28EC variant specifically targets applications needing precise voltage supervision with manual reset capabilities in a compact surface-mount form factor.

Supervisors Replacement Considerations

Check for other R3134N variants with identical 2.8 V thresholds and CMOS outputs. Verify package compatibility with SOT-23-5 footprints. Ensure replacement parts support manual reset and battery backup functions if these are critical to the design.
