R3114Q461C-TR-FE

Supervisors Overview

The R3114Q461C-TR-FE is a single-channel voltage detector IC from the R3114x series manufactured by Ricoh Electronic Devices Co., Ltd. It operates within a supply voltage range of 0.7V to 10V and features a fixed detection threshold of 4.6V with high accuracy. The device utilizes a CMOS output driver in a push-pull or totem pole configuration, providing an active-low reset signal. Typical reset delay time is 40µs. It functions reliably across an industrial temperature range of -40°C to +85°C and is housed in a compact SC-82AB (SOT-343) surface-mount package.

Supervisors Feature Summary

• CMOS-based architecture enabling operation at extremely low voltages starting from 0.7V
• High detector threshold accuracy for precise system supervision
• Ultra-low supply current consumption suitable for battery-powered applications
• Integrated hysteresis circuit to prevent output oscillation during threshold transitions

Supervisors Applications

• System reset circuits for microprocessors and digital logic
• Battery backup switching mechanisms
• Low voltage detection in portable electronic devices
• Power supply monitoring in industrial control systems

Supervisors Procurement Notes

Verify the manufacturer designation as Ricoh Electronic Devices Co., Ltd., noting that Nisshinbo Micro Devices may appear in some distributor listings due to corporate history. Confirm the SC-82AB package type and 4.6V threshold match the design requirements. Ensure the tape and reel packaging aligns with automated assembly processes. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. The CMOS push-pull output is suitable for direct interfacing with digital inputs without external pull-up resistors. Consider the 40µs typical reset delay for timing-sensitive applications. The wide operating voltage range allows compatibility with various power rails. Verify thermal performance within the specified -40°C to +85°C range for the intended environment.

Supervisors Part Context

This part belongs to the R3114x series of low voltage detectors. The series includes variants with different fixed thresholds and output types. Ricoh Electronic Devices specializes in precision analog and mixed-signal ICs. The R3114x series is designed for high reliability and low power consumption, targeting applications where stable voltage monitoring is critical for system integrity and safety.

Supervisors Replacement Considerations

Check for exact pin-compatible substitutes within the R3114x series with identical 4.6V thresholds. Verify if alternative manufacturers offer equivalent CMOS supervisors with matching reset delays and package dimensions. Ensure any replacement maintains the same active-low reset polarity and push-pull output characteristics to avoid circuit redesign.
