R3114Q421A-TR-FE

Supervisors Overview

The R3114Q421A-TR-FE is a supervisory circuit manufactured by Nisshinbo Micro Devices, belonging to the R3114Q series. It functions as a voltage detector with an operating voltage range starting from 0.5V and maintains a detection accuracy of 0.8%. The component is housed in an SC-82AB-4 package and is supplied in reel packaging.

Supervisors Feature Summary

• Provides precise voltage monitoring with specified accuracy levels
• Operates at low input voltages starting from 0.5V
• Designed for integration into power management systems

Supervisors Applications

• Battery voltage monitoring
• Power supply supervision
• System reset generation

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct voltage thresholds and package types. Confirm RoHS compliance status through manufacturer documentation before procurement. Ensure ordering quantities align with factory reel requirements.

Supervisors Selection Notes

Select this component when low-voltage operation down to 0.5V is required. The SC-82AB-4 package suits space-constrained designs. Verify that the 0.8% accuracy meets system tolerance requirements compared to other series variants.

Supervisors Part Context

This part belongs to the R3114Q series of supervisory circuits under Nisshinbo Micro Devices' PMIC portfolio. It shares functional similarities with the R3114N series but utilizes a distinct SC-82AB-4 package format instead of SOT-23-5.

Supervisors Replacement Considerations

R3114Q401A-TR-FE and R3114Q451A-TR-FE are confirmed substitutes within the same series offering different detection voltages.
