R3116N481A-TR-FE

Supervisors Overview

The R3116N481A-TR-FE is a supervisory circuit voltage detector manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 0.5 V to 6 V and features a threshold voltage of 4.8 V with an accuracy of 0.8%. The device utilizes a CMOS open-drain output and includes a reset delay function. It is designed for low-power applications, consuming only 1.5 µA of operating current. The component supports battery backup switching and is housed in a compact SOT-23-5 package suitable for surface-mount technology.

Supervisors Feature Summary

• Provides precise voltage monitoring with high detection accuracy
• Operates at ultra-low power consumption levels
• Includes integrated reset delay functionality

Supervisors Applications

• Battery-powered portable electronic devices

• Low-voltage detection circuits

Supervisors Procurement Notes

Verify the specific threshold voltage code corresponding to 4.8 V during procurement. Confirm that the SOT-23-5 package variant matches the design requirements. Ensure compliance with RoHS directives as specified in the official documentation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.8 V threshold is required for system supervision. Consider the 1.5 µA quiescent current for battery life optimization. The open-drain output requires appropriate pull-up configuration. Verify thermal performance within the -40°C to +85°C operating range for the target application environment.

Supervisors Part Context

This part belongs to the R3116N series of low-voltage detectors from Nisshinbo Micro Devices. The series offers various threshold voltages while maintaining consistent accuracy and low power characteristics. The R3116N481A-TR-FE specifically targets applications requiring reliable monitoring at higher voltage thresholds compared to lower-voltage variants in the same family.

Supervisors Replacement Considerations

Compatible substitutes include other R3116N series parts with different threshold codes, such as R3116N471A or R3116N491A, provided the voltage level adjustment is acceptable. Ensure pin compatibility and package similarity when considering cross-series replacements.
