R3112Q181C-TR-FE

Supervisors Overview

The R3112Q181C-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices, designed for supervisory circuit applications. It features a fixed threshold voltage of 1.8 V with an overvoltage threshold of 1.836 V and an accuracy of 2%. The device operates within a power supply range up to 6 V and consumes a working current of 1 uA. It provides a reset delay time of 100 ms and supports a backup function. The component is housed in an SC-82AB-4 package and functions as a single-input voltage detector with CMOS open-drain output.

Supervisors Feature Summary

• Provides low voltage detection with a dedicated output capacitor type for generating an output delay.
• Includes a backup switch function to maintain monitoring during power transitions.
• Features a CMOS open-drain output interface suitable for direct logic connection.

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices
• Supervising power supply integrity in embedded systems
• Preventing malfunction due to undervoltage conditions in microcontroller circuits

Supervisors Procurement Notes

Verify the specific suffix 'C' against the official datasheet to confirm the exact threshold voltage and package variant, as ordering suffixes define critical electrical parameters. Ensure the SC-82AB-4 package footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's environmental documentation prior to final procurement approval.

Supervisors Selection Notes

Select this component when a precise 1.8 V threshold is required for single-channel voltage monitoring. The 100 ms reset delay helps filter transient noise before triggering a system reset. Consider the 1 uA operating current for low-power battery applications. Verify that the open-drain output capability aligns with the downstream logic level requirements of the target application.
