R3111H581A-T1-FE

Supervisors Overview

The R3111H581A-T1-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 0.7 V to 10 V and features a fixed threshold voltage of 5.8 V. The device utilizes an SOT-89-3 surface-mount package and provides an open-drain output type. It supports battery backup switching functionality without manual reset or watchdog timer capabilities. The component is rated for operation between -40°C and +85°C, ensuring reliability in standard industrial environments.

Supervisors Feature Summary

• Provides precise low-voltage monitoring with a fixed detection threshold
• Supports battery backup switching to maintain system state during power transitions
• Utilizes an open-drain output configuration for flexible interfacing

Supervisors Applications

• Battery-powered equipment requiring under-voltage protection
• Portable devices needing reliable power management
• Industrial control systems utilizing voltage supervision

Supervisors Procurement Notes

Verify the specific suffix T1-FE against official datasheets to confirm package and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOT-89-3 package. Cross-reference the 5.8 V threshold requirement with system design constraints to prevent false triggering. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Supervisors Selection Notes

Select this component when a fixed 5.8 V detection level is required for system supervision. The open-drain output allows for easy connection to various logic levels. Consider the SOT-89-3 package size for space-constrained designs. Verify that the 10 V maximum input voltage aligns with the highest expected supply rail in the application circuit.

Supervisors Part Context

This part belongs to the R3111H series of low voltage detectors from Nisshinbo Micro Devices. The series offers various threshold voltages to suit different monitoring needs. These devices are designed for efficient power management in portable and industrial electronics, providing stable operation across a wide temperature range.

Supervisors Replacement Considerations

Check the R3111H581C-T1-FE variant if a CMOS output is preferred over the open-drain configuration. Other series members may offer different thresholds but require verification of pinout and package compatibility.
