R3118N301C-TR-FE

Supervisors Overview

The R3118N301C-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It features a CMOS open-drain output and includes a dedicated sense pin for accurate monitoring. The device operates within a supply voltage range up to 6 V and provides an 80 µs reset delay time. It is housed in a compact SOT-23-5 package suitable for surface mount applications.

Supervisors Feature Summary

• Integrated sense pin for enhanced voltage monitoring accuracy
• CMOS open-drain output configuration
• Compact SOT-23-5 surface mount packaging

Supervisors Applications

• Battery-powered electronic devices requiring low voltage supervision
• Portable consumer electronics with limited power budgets
• Embedded systems needing reliable power failure detection

Supervisors Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm threshold voltage and tolerance specifications. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the SOT-23-5 footprint matches the target PCB design constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a dedicated sense pin is required for precise voltage tracking separate from the main supply input. The open-drain output allows for flexible logic level interfacing. Consider the 80 µs delay for timing-sensitive reset sequences in microcontroller-based designs.

Supervisors Part Context

This part belongs to the R3118N series of low voltage detectors from Nisshinbo Micro Devices. The series is characterized by low current consumption and high accuracy, designed for battery-operated equipment. The R3118N variant specifically integrates a sense pin to improve monitoring precision under varying load conditions.

Supervisors Replacement Considerations

Cross-reference with other R3118N variants sharing the same SOT-23-5 package and 6 V maximum rating. Verify that substitute parts maintain the open-drain output type and compatible reset delay characteristics.
