R3118N091C-TR-FE

Supervisors Overview

The R3118N091C-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 1 V to 6 V and features a threshold voltage of 0.9 V. The device utilizes an SOT-23-5 package for surface mount installation. It provides a CMOS output type with an open-drain configuration and includes a reset delay time of 80 µs. The component supports battery backup switching and lacks manual reset or watchdog timer functions. It operates reliably between -40°C and +85°C.

Supervisors Feature Summary

• Integrates a dedicated sense pin for accurate voltage monitoring
• Provides output delay functionality via external capacitor connection
• Supports battery backup switching for continuous operation during power transitions

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices
• Detecting under-voltage conditions in embedded systems
• Providing reset signals for microcontrollers in low-power applications

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct threshold voltage and output configuration. Confirm package availability and reel specifications prior to ordering. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Ensure environmental compliance requirements match project specifications.

Supervisors Selection Notes

Select this component when a precise 0.9 V detection threshold is required for low-voltage monitoring. Consider the open-drain output and 80 µs delay characteristics for system timing compatibility. Evaluate the SOT-23-5 footprint constraints against available board space. Compare power consumption metrics if battery life optimization is critical for the application design.

Supervisors Part Context

This device belongs to the R3118N series of low voltage detectors from Nisshinbo Micro Devices. The series is characterized by high accuracy and low current consumption suitable for portable electronics. The R3118N variants typically include sense pins and output delay capabilities, distinguishing them from basic voltage detectors without these advanced monitoring features.

Supervisors Replacement Considerations

Check for direct substitutes within the R3118N series offering different threshold voltages. Verify pinout compatibility before considering alternative packages. Consult manufacturer cross-reference guides for verified equivalent parts.
