R5107G381A-TR-FE

Supervisors Overview

The R5107G381A-TR-FE is a single-channel voltage supervisor IC from Nisshinbo Micro Devices. It features a fixed reset threshold voltage of 3.8V with an open-drain or open-collector output that asserts low. The device includes a minimum reset timeout period of 340ms to ensure stable system recovery. It operates within a temperature range of -40°C to +105°C and is housed in an 8-LSSOP package.

Supervisors Feature Summary

• Integrates a voltage detector with a watchdog timer function for comprehensive system monitoring.
• Provides a dedicated reset signal via an open-drain/open-collector output interface.
• Ensures reliable operation across industrial temperature ranges.

Supervisors Applications

• Embedded system power supply monitoring
• Microcontroller reset circuitry
• Industrial control unit supervision

Supervisors Procurement Notes

Verify the specific suffix 'TR-FE' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm the 3.8V threshold matches your design specifications, as other variants in the R5107 series offer different voltage levels. Ensure compatibility with the 8-LSSOP footprint during PCB layout review.

Supervisors Selection Notes

Select this component when a fixed 3.8V detection level is required for CMOS-based supervisory circuits. The open-drain output allows flexibility in interfacing with various logic families. Consider the 340ms minimum timeout if fast transient immunity is not the primary design constraint.

Supervisors Part Context

This part belongs to the R5107 series of supervisory circuits designed for monitoring single voltage rails. It combines voltage detection capabilities with reset generation functions. The series supports multiple threshold voltages to accommodate diverse application requirements while maintaining a compact surface-mount form factor.

Supervisors Replacement Considerations

Direct substitutes include other R5107G variants with identical 8-SSOP packaging but different threshold voltages, such as R5107G291A-TR-FE (2.9V) or R5107G431A-TR-FE (4.3V), provided the voltage level adjustment aligns with system needs.
