R3114K271A-TR

Supervisors Overview

The Ricoh R3114K271A-TR is a CMOS-based voltage detector IC featuring a fixed output threshold of +2.7V. It operates within a supply voltage range starting from 0.5V and provides high accuracy of ±0.8%. The device includes an internal output delay circuit to prevent false triggering during power-up or noise events. It utilizes a DFN(PLP)1010-4 package with four pins, supporting open-drain or open-collector output configurations for flexible interface compatibility in low-voltage monitoring applications.

Supervisors Feature Summary

• CMOS technology enabling operation at ultra-low voltages down to 0.5V
• Built-in output delay circuit to ensure stable detection under transient conditions
• High threshold accuracy of ±0.8% for precise voltage monitoring
• Open-drain/open-collector output configuration for system flexibility

Supervisors Applications

• Battery-powered portable devices requiring low-voltage supervision
• Microprocessor reset circuits in embedded systems
• Voltage monitoring in battery-operated consumer electronics
• Power management systems in compact mobile devices

Supervisors Procurement Notes

Verify the manufacturer designation as Ricoh, also referenced as Nisshinbo Micro Devices, to ensure component authenticity. Confirm the package type matches the DFN(PLP)1010-4 specification and that the output configuration aligns with system requirements. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the lead-free marking is present on the component body for quality assurance purposes.

Supervisors Selection Notes

Select this component when a fixed 2.7V threshold is required for voltage supervision. The low operating voltage of 0.5V makes it suitable for single-cell battery applications where other detectors may fail. The high accuracy ensures reliable reset generation without unnecessary resets due to threshold drift. Consider the open-drain output if level shifting or wired-OR connections are needed in the design.

Supervisors Part Context

This part belongs to the R3114K series of voltage detectors from Ricoh. The series offers various threshold voltages and accuracy levels. The '271' suffix indicates the specific 2.7V threshold setting. The '-TR' suffix denotes tape-and-reel packaging for automated assembly. This series is designed for low-power applications requiring precise voltage monitoring in small packages.

Supervisors Replacement Considerations

The R3112x Series is documented as a related CMOS-based voltage detector family from Ricoh with similar low-voltage capabilities. Verify pinout compatibility and threshold voltage matching before substitution. Ensure the replacement part supports the required output delay and package dimensions for direct board integration.
