R3111D511B-TR-FE

Supervisors Overview

The R3111D511B-TR-FE is a CMOS-based power supply support circuit manufactured by Ricoh Electronic Devices Co., Ltd. It functions as a low voltage detector with a fixed detector threshold voltage of 5.1V. The device operates within an ambient temperature range of -40°C to 85°C and utilizes a SON1612-6 package containing six terminals. It features an open-drain or open-collector output configuration with high-active reset functionality. The maximum reset timeout is specified as 100µs. The component is lead-free, RoHS compliant, and classified under EAR99.

Supervisors Feature Summary

• CMOS technology integration for ultra-low supply current operation
• Fixed internal detector threshold voltage ensuring high accuracy without external adjustment
• Open-drain or open-collector output driver configuration

Supervisors Applications

• System reset circuits in electronic devices
• Low voltage detection in portable equipment
• Power supply monitoring in industrial control systems

Supervisors Procurement Notes

Verify the manufacturer designation on official documentation, as Nisshinbo Micro Devices Inc. also lists this part number in distribution channels. Confirm the specific package type matches the SON1612-6 specification rather than SOT variants found in other series members. Ensure the threshold voltage requirement aligns with the fixed 5.1V parameter before procurement.

Supervisors Selection Notes

Select this component when a fixed 5.1V detection threshold is required for system supervision. The open-drain output necessitates appropriate pull-up resistor selection based on the load voltage. Verify that the operating voltage range covers the minimum system voltage to ensure reliable detection. The SON1612-6 package requires compatible PCB footprint design.

Supervisors Part Context

This component belongs to the R3111x series of voltage detector ICs produced by Ricoh Electronic Devices Co., Ltd. The series includes various models with different threshold voltages and output types. Ricoh is a subsidiary of Ricoh Company, Ltd., which focuses on digital services and electronic components manufacturing.

Supervisors Replacement Considerations

R3111N511A-TR-FE offers similar functionality with a 5.1V threshold but uses a SOT-23-5 package. R3111Q252C-TR-FE provides a 2.5V threshold in an SC-88A package. Cross-reference datasheets for pin compatibility and electrical specifications before substitution.
