R3111Q141C-TR-FE

Supervisors Overview

The R3111Q141C-TR-FE is a low voltage detector from the Nisshinbo Micro Devices R3111Q series, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 0.7 V to 10 V and features a threshold voltage of 1.4 V with an accuracy of ±2%. The device utilizes a CMOS output type and includes a backup function for battery retention. It is housed in an SC-82AB-4 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with high accuracy for reliable system reset generation
• Supports battery backup mode to maintain internal state during power loss
• Features ultra-low current consumption for extended battery life in portable applications

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage monitoring
• Embedded controllers requiring stable reset signals

Supervisors Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct output configuration and package type. Confirm that the SC-82AB-4 footprint matches your PCB design requirements. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process. Ensure operating conditions remain within the specified thermal and voltage limits.

Supervisors Selection Notes

Select this component when a fixed 1.4 V threshold is required for single-input voltage monitoring. The CMOS output makes it suitable for direct interfacing with digital logic circuits. Consider the SC-82AB-4 package size constraints and the need for backup functionality. Verify that the 10 V maximum input voltage aligns with your system's power rail specifications.

Supervisors Part Context

This part belongs to the R3111Q series of supervisory circuits, which are optimized for low-power applications. The series offers various threshold voltages and output types to accommodate different system requirements. The Q-series typically denotes specific package or performance variations within the broader R3111 family.

Supervisors Replacement Considerations

Check for other R3111Q variants with identical 1.4 V thresholds but different output configurations if pin compatibility allows. Verify equivalent packages such as SC-82AB-4 from other manufacturers offering similar low-voltage detector specifications.
